Version 2.01.04 August 2020

If you are upgrading from a PAMGuard core release (1.15.xx), PAMGuard Version 2 contains major updates. You should read and understand the notes listed for Beta Version 2.00.10 before proceeding with installation and use of this version.

This version of PAMGuard has been bundled with Java 13 (release 13.0.1). PSFX files generated in previous beta releases (2.xx.xx) should be compatible with this version, and vice-versa. PSF files generated in core releases (1.15.xx) can be loaded in this version, but will be converted to PSFX files when PAMGuard exits.

Upgrades

  1. 1.        Better way of coupling scrollers in User Display panels - see new options in main menu.
  2. 2.        Added Matched Template Click Classifier. Classifies clicks based on an ideal template to match and a template to reject. An example of this is to classify beaked whale clicks in an environment with dolphin clicks.
  3. 3.        Added zoom in/out to Raw Data plugin display in spectrogram.
  4. 4.        Added ability to read differential GPS data.
  5. 5.        Added check for duplicate settings in the psf file when exiting Pamguard. If duplicate settings are found, user is given the option to leave them in the psf or get rid of them. Duplicate settings are ignored by Pamguard, but can cause the psf file to grow large over time.
  6. 6.        New features in PAMGuard Beta mean that psf files created with new versions are not compatible wth earlier versions and all configuration data may be lost if an attempt is made to open newly created psf files with older versions. We have therefore changed the file extension of psf files to .psfx in new Beta releases. Beta releases will still load the older psf files, but when the configuration is saved, the original psf file will remain untouched and data will be written to a psfx file with the same directory and name.

Beta Version 2.00.10 June 2017

PAMGuard Version 2 contains major updates. You should read and understand these notes before proceeding with installation and use of this version. These changes have been funded under contract to NOAA Fisheries, contract no. WE-133F-16-SE-1126.

Binary File Structural Changes

The Binary File structure has changed to accommodate additional information for each unit of data stored. This means that any data generated with PAMGuard Version 2.00.00 and above will not be compatible with older versions of PAMGuard. If you open older data sets with the PAMGuard Viewer the older data will be converted to the new format (see below for details).

The most significant change in the binary file format is the addition of a Unique Data Identifier (UID) to each unit of data. This is intended to aid in offline analysis by making it easier for the user to link what they are seeing on different PAMGuard displays and also to link with any data post processed in Matlab or other custom analysis software. UID’s are also added to PAMGuard database tables.

Converting Old Data

If old data are opened with the PAMGuard viewer they will automatically be converted. For safety, the original binary files will not be overwritten and the new data will be placed in a new folder on your computer with the same path as the old data, but suffixed with ‘_WithUID’, e.g. if your binary data were previously stored in the folder C:\MySurvey\binarydata the new data will be written to C:\MySurvey\binarydata_WithUID.

The additional UID column will be added to all database tables and populated with unique values. For data which are stored in both the binary files and in database tables, the same UID’s will be used in both data stores.

New Displays

A new time based scrolling display has been added to PAMGuard which can display multiple types of data on the same time axis. It can for instance be used to display bearings to whistles on a bearing-time type display similar to that commonly used in the click detector. Composite display graphs containing data from more than one detector are also possible. For details, see the PAMGuard help file (Displays / Time Display FX). Note that this display is only available if you are running Java 8 or later.

Event Marking and the Detection Group Localiser

A new system of event marking which can be used both online and offline has been added to PAMGuard. Details are in the PAMGuard help file (Displays/Display Marking). Data can be selected on the Map, the Spectrogram Display and the new Time Display FX in a similar way and sent to other PAMGuard modules. The new marking and data selection system works with the new Detection Group Localiser. The Detection Group Localiser extends the functionality which always existed in the click detector to other types of data (e.g. Whistles) so that they can be grouped and tracked using target motion analysis in a similar way. Details of the Detection Group Localiser are in the PAMGuard help files (Localisation/Detection Group Localiser).

Display Colours

A new system for handling display colours has been implemented across all PAMGuard displays. This gives greater flexibility to the user to control how data units are shown. For instance, you might simply want to show clicks in blue and whistles in green. However, for clicks and whistles that have been assigned to a Detection Group, you may want to colour them by the colour assigned to the group.

Using Old PAMGuard Configurations

Old PAMGuard configurations will work with the new version. However please note the following:

  1. New classes will be added to the configuration files, so they will no longer work with older PAMGuard versions.
  2. Display colour options will be lost and most data displayed on the map may default to black. This is due to the above changes to how colours are managed. Changing back to the colours of your choice is relatively simple through the PAMGuard GUI.

Version 1.15.11 May 2017

Bug Fixes

  1. Bug 317. Rocca Module Data Purging. The ROCCA module was not performing data purging when using classifiers developed for Hawaii/Temperate Pacific/North Atlantic datasets. This has been corrected.
  2. Bug 320. Pamguard stopped reading Click Detector Event data from database when target motion analysis information was encountered. Corrected.
  3. Bug 321. Problem reading Soundtrap 4 files. Fixed.

Upgrades

  1. Added Copy-to-Clipboard button to Warning dialogs, to store error messages and stack trace information on the Windows clipboard. This information can then be easily pasted into emails, text documents, etc when contacting Pamguard support.
  2. Enhancements and bug fixes made to Difar module during 2017 ACE voyage.
  3. Rocca Module: added StartHr, ProportionWhists and ProportionClicks parameters to Event classifier
  4. The installer now allows the user to enter command line switches/parameters to be included in *.ini files.

Version 1.15.10 March 2017

Bug Fixes

  1. Bug 308. Map Overlay Control. Storage of data saying what get's plotted on each map and for how long became corrupted and the list grew to a ridiculous size. Code has been put in place to a) stop it happening again and b) to repair any configuration files which are corrupted. Corrupted files will be slow to load, slow to save and will be > several megabytes in size. It may be necessary to delete the PamguardSettings table in any databases since these too may have become oversized which will slow down viewer mode PAMGuard start-up.
  2. Bug 309. Rocca would crash when the user would press the classify button after the contour was recalculated. This has been corrected.
  3. Bug 310. When exiting Viewer mode, PAMGuard queries the user whether they are sure they want to exit without saving even though they selected Save and Exit. Corrected, and added an Exit without Save option.
  4. Bug 311. When double-clicking on a psf file to start PAMGuard, the working directory is set as the location of the psf and not as the installation folder. The library subfolder (\lib or \lib64) uses a relative path from the working folder, and therefore is set incorrectly. This has been fixed.
  5. Bug 314. If PAMGuard is started by double-clicking on a psf, nothing happens when the user selects save as new configuration. This has been fixed.
  6. Bug 315. code searched for file in working folder, which is the installation folder when starting PAMGuard using a shortcut link. But when double-clicking on a psf, the working folder is the location of the psf. This has been fixed.
  7. Bug 316. Another error reading metadata for Dtag and SoundTrap files has occurred due to a format change in dTag metadata. This has been fixed.

Version 1.15.09 January 2017

BugFixes

  1. Bug 306. Certain methods have been querying AcousticDataUnit.getDuration and expecting to receive a response in milliseconds. However, getDuration actually returns the number of samples.  This has been corrected.

Plug-Ins

A major change in this version of PAMGuard is how plug-ins are managed. PAMGuard now has the ability to dynamically load plug-in modules (saved as jar files) at runtime. This will greatly simplify the process of testing and distributing newly developed modules, since only a small jar file will be required rather than a new bespoke PAMGuard installation.

Module code development remains largely unchanged, in most cases simply requiring the addition of an interface class.  Instructions for the development of new modules utilizing the plug-in scheme can be found here.  Plug-in modules can be downloaded from the PAMGuard website here, but developers are encouraged to host and maintain their own modules.

Modules of interest to the general PAM community will remain as part of the core PAMGuard installation. However, specialized modules which are useful to only a small number of users have been removed and are available as a separate download. The following modules have been removed:

  1. Resource Monitor
  2. WILD ArcGIS Interface
  3. Workshop Demo Detector
  4. Echo Detector and IPI Demo (bundled together, due to dependencies)

Other Changes

The installer has been updated to handle both 64 bit and 32 bit installations. PAMGuard psf files are now registered in the Windows Registry, so double-clicking on a psf file should run PAMGuard in normal mode (as opposed to Viewer or Mixed modes). Note that the Windows Registry can only hold a single executable reference for psf files; therefore, for users with multiple installations of PAMGuard, double-clicking on a psf will run the most-recently installed version of PAMGuard on the system.

Version 1.15.08 November 2016

This release contains one bug fix.

Bug Fixes

  1. Bug 307. Unpacker for Sound trap dwv files was not working correctly. This is now fixed.

Version 1.15.07 November 2016

This release contains two bug fixes.

Bug Fixes

  1. Bug 303. Some ASIO sound cards not working with either ASIO system in PAMGuard. For the PAMGuard ASIO system, this was due to a data format used by some sound cards never being properly implemented. For the “New ASIO system” which is based on jAsioHost, the unpacking of that format contained a bug which returned incorrect numbers, so data were swamped with noise. Both systems are now fixed. By preference, users should use the PAMGuard ASIO system since the JAsioHost based system seems to drop samples when many channels are running at high sample rate.
  2. Bug 305. Date and Time not being correctly extracted from wav files created using SoundTrap recorders. Fixed by correctly finding and unpacking information in the accompanying xml log files that come with SoundTrap files.

Version 1.15.06 November 2016

This release contains bug fixes from release 1.15.05, mostly concerning the new target motion analysis methods. Bugs were found in several places in the system, affecting calculations using all three methods: Least Squares, 2D Simplex and 3D Simplex. To the best of our knowledge, all issues are now resolved.

Bug Fixes

  1. Bug 291. Click Detector Click Classifier: If this is set to "none" the click detector will freeze / crash and will put the psf file into a state where it will never load again. Incredibly, this bug seems to have been in place for several years and no one has come across it until now. It's fixed.
  2. Bug 292. Incorrect labels on Target Motion panel in viewer - 3D algorithm was labelled as 2D.Fixed
  3. Bug 293. Errors displayed in the click detector target motion panel were wrong in the graphics for the Simplex localisers and wrong in the tabulated data for the least square model. Both fixed.
  4. Bug 294. Click classifier was crashing when the 'min amplitude' option was used. This is fixed.
  5. Bug 295. If a click has a total length of a single sample, the code attempting to estimate the time delay between channels would crash. This is now fixed. This could only occur if both pre sample and post sample were set to 0 in the click detector, which is generally not a good idea, so this bug may have been there for some time, it's just that no one noticed before. Fixed
  6. Bug 296. Context menu popping up in click detector when marking clicks in Viewer mode. This has been fixed so that in viewer mode, the menu will only appear when you right click on the display.
  7. Bug 297. Airgun display was not correctly showing itself at fixed locations, but always following the vessel track. This is now fixed.
  8. Bug 299. Threading Hydrophone locator. Bug found in hydrophone heading calculation has been fixed.
  9. Bug 300. GUI Tab panel selections were not being restored correctly when PAMGuard displays were split across multiple frames. Fixed.
  10. Bug 301. Multiple errors in the target motion module have been fixed.
  11. Bug 302. Target motion calculations taking too long when many clicks are included in a track. Mostly a problem when using automatic click train id. Fixed by setting an optional maximum number of clicks to use in a track.

Version 1.15.05 September 2016

Bug Fixes

  1. Bug 273. Sound files in viewer data map. These were not being correctly catalogues in the datamap when using the PAMGuard viewer which meant that PAMGuard was not correctly loading sound data during offline analysis. This is now fixed.
  2. Bug 287. Slow database. This has been solved by setting the default behavior of the database to have Auto Commit set to 'off'
  3. Bug 288. Fixed problem of missing help file image
  4. Bug 290. Click bearings on spectrogram display plug in were reversed if the first hydrophone was behind the second hydrophone in the configuration. This is now fixed so that it displays the same bearings as the main click detector display.

Target Motion Analysis

A major piece of work has been undertaken to improve the Target Motion tracking with PAMGuard. Details are available in the online help. Users of the Click Detector will notice the following changes:

  1. There is now a choice of least squares and Simplex based algorithms for real-time animal tracking. The improved algorithms also provide better error information both for display on the map and for storage in the database.
  2. The number of data streams associated with the click detector has been tidied up so that there are a) All Click, b) Tracked Clicks (those which are part of an event) and c) Events.
  3. When tracking online, all the click marking information is written to the same database tables as are used for offline target motion analysis. This means than when reviewing data offline, the tracks created in real time are now available for review and further analysis.
  4. A number of user options are now available for automatic click train identification and tracking.
  5. The automatic click train identification is now using the same internal structures as the manual tracking, so it's possible to combine automatic and manual tracking.
  6. Improved options are available to the user, via the click detector bearing time display, to correct and relabel clicks / entire click trains.

Developers will hopefully find that the target motion code has been improved in a way which will make it much easier to provide target motion localization for other detection types (e.g. whistles) in the future.

Other Features

Logger Form Design

A GUI driven system for designing Logger forms has been released. Currently, this feature has no online help, but is reasonably intuitive compared to the old method of typing directly into the database.

Improved Number handling

Users have often found that PAMGuard can be 'jumpy', i.e. the spectrogram does not scroll smoothly, but pauses for a second every few seconds. This is caused by the Java garbage collector cleaning up unused objects in memory. With 64 bit versions, which allow for more memory, some of these pauses were becoming quite long (due to the increased amount of memory that needed to be cleaned up). In some circumstances, these pauses were making data acquisition systems unstable. We have therefore entirely rewritten the way in which PAMGuard handles arrays of spectrogram data (complex numbers) so that instead of large numbers of small Java objects there are now fewer, larger, simpler java objects. These reduce processing delays for garbage collection and give an overall speed improvement, but will otherwise not be noticed by users.

Click Detector RainbowClick file output

This feature has been removed since it has been obsolete for several years. Users should use the PAMGuard binary storage system for Click Detector data.

Version 1.15.04 July 2016

Bug Fixes

A number of bug fixes and code improvements have been made since V 1.15.03:

  1. Bug 272. File types: Some File Open / File Save dialogs were allowing selection of all file types. e.g. Save Configuration As, Section of whistle classifier training file, Map file Selection, These have now been changed so that only the correct type of file can be selected.
  2. Bug 274. GPS Memory leak. A Memory leak associated with GPS data collection has been found which could cause PAMGuard to run out of memory after a day or two's operation. This has now been fixed.
  3. Bug 275. Painting of thumbnail on the Map display time slider. Have fixed a small problem in the graphical display. The visibility of components on this slider has also been improved and a log time scale option is available to facilitate in map data display.
  4. Bug 276. The default hydrophone sensitivity was -201dB re 1V/uPa. This was supposed to be used with a default preamp gain of 30dB. For some reason gain was no longer being added. We have therefore set a default sensitivity of -170dB and left gain at zero. This is more typical of many hydrophones in use today. 
  5. Bug 277. Text fields in classifier dialog were not large enough to display times greater than 10ms. We have increased length of text fields in the dialog.
  6. Bug 278. Have future proofed against potential binary file format changes in future releases. New PAMGuard releases will always be able to open older binary files, however, with previous PAMGuard releases if a newer file format was opened, then PAMGuard was unable to check that the file format was newer and would attempt to read the files and might even corrupt them. Now it will recognise that it cannot open the files, display appropriate error messages and not attempt to read the files. NOTE that at this time there are no planned file format changes and that this is purely a future proofing exercise.
  7. Bug 279. GUI Resizing: The whole PAMGuard GUI would suddenly resize to something very small when a dialog is opened. This has been traced to improper use of a common dialog component SourcePanel which tries to repack its parent Window. Some programmers had inadvertently set it to repack the main PAMGuard GUI instead. This has been Fixed.
  8. Bug 280. Recorder control option to automatically restart recording were causing confusion. It was working in that the recorder would return to its previous state, but it was sometimes difficult for users to set it so that recording would always start as soon as PAMGuard started. More sensible and easy to understand options have been developed in a new options dialog.
  9. Bug 281. Click classification dialog has grown too big to fit on the screen. The options have now been split across three tabbed panes which solves the problem.
  10. Bug 282. Quiet clicks causing too many false classifications. An additional option has been added to the click classifier to limit a class to a range of amplitude.
  11. Bug 283. The spectrogram display was not displaying data in Viewer mode. This has been traced to a problem in offline data mapping and has been fixed.

Version 1.15.03 April 2016

A single bug fix concerning import from Access databases to SQLite.

  1. Bug 271. Problem 1 was that the incorrect settings were being imported into the new database. Problem 2 was that indexing of imported click events in the new database was incorrect. Both these issues have now been fixed.

Version 1.15.02 March 2016

A number of small bug fixes following release of 1.15.00.

Bug Fixes

  1. Bug 266. Clip generator crashed in viewer when the path for output files was not defined even if files were not being created. Fixed.
  2. Bug 267. Click detector not calculating correct bearings when multiple hydrophone pairs with different separations were used. Fixed.
  3. Bug 268. ROCCA module was not saving WAV file clips. Fixed.
  4. Bug 269. Whistle and Moan detector paired bearing localiser was not working. This localizer searches for matching whistles on pairs of hydrophones. Bearings from each pair are crossed to create a localization. Fixed.
  5. Bug 270. Improved file names display in Pamguard Viewer offline data map and datagram creation.

Version 1.15.00 February 2016

Beta Version 1.15.00 64 bit and Core version 1.15.00 32 bit. Both using identical Java core software but linking to different libraries for control of sound input devices.

This is the first release of a 64 bit version of PAMGuard. As with the 32 bit version a number of C language libraries are required to interface to external sound cards and other data acquisition devices. These have been extensively tested on several different computers, but may not be as stable as the 32 bit versions. Please report any problems immediately to the PAMGuard team.

Other Changes

Updated the configuration file WMM.COF for World Magnetic Model to the latest 2015-2020 version. See https://www.ngdc.noaa.gov/geomag/WMM/soft.shtml

Small changes to the ROCCA classification module:

  1. Remove white spaces and parenthesis characters from RoccaContourStats header row
  2. Report 'N/A' for min time between detections, if there is only 1 detection
  3. Add ability to load standard notes and use in RoccaParameters dialog window
  4. Fixed Rocca multi-threading problem which caused Click Detector to send same click multiple times

Bug Fixes

  1. Bug 253. Database import fails when Access database contains queries. Fixed.
  2. Bug 254. Lookup lists failing in imported SQLite databases. This was caused by the system 'padding' topic's with blank spaces and is now fixed.
  3. Bug 256. Map not updating. Graphics updating was only happening when new GPS data arrived and therefore didn't update when using static hydrophones. Fixed so that graphics update correctly.
  4. Bug Sound recorder missing a few samples between files. The sound recorder wav file output system has been rewritten in a much simpler form and now won't lose samples between consecutive files when new files are started automatically. It will also start new files on integer second or minute boundaries when file durations are set to a maximum fixed value.
  5. Bug 262. Access to SQLite database conversion. This would fail when tables were present which were not created by PAMGuard.  Fixes have been put in place for spaces in the table name or for not having an 'Id' column. Fixes have not been implemented for spaces in a column name or use of a reserved word as a column name, however if either of these problems do exist it will no longer crash but issue a clear warning and carry onto the next table.

 

Version 1.14.00 Beta, September 2015

The format of configuration files has changed for version 1.14.00. Older configurations will load with this new version, but configurations saved with 1.14.00 may not open correctly with earlier versions.

PAMGuard Versions 1.14.00 and above will work with Java 8. PAMGuard will continue to work with Java 7, but support for Java 7 will be removed entirely during 2016. This means that the Microsoft Access Database interface will no longer be available. Version 1.14.00 will continue to support Microsoft Access so long as you don't upgrade your Java version to Java 8.

An alternative database interface has been provided in the form of SQLite which has been extensively tested with all PAMGuard modules. Limited connectivity to MS Access databases using the open source UCanAccess database connection is provided in Viewer mode which will allow users to convert old Access databases to SQLite or MySQL depending on preference. See the PAMGuard help file for further details.

Other Changes

  1. Feature Request 45. Module settings import. Functions have been provided which enable users to import the settings for individual modules into new configurations. See the help file for details.
  2. Feature Request 45. Click classification settings export / import. Click classification settings can be exported individually to files and imported into other click detector configurations. See the help file for details.
  3. GPS Loading into PAMGuard Viewer. This has been modified so that the rules governing GPS data collection and storage also apply when loading data from the database. For instance, if you've stored all GPS data, you've probably got a record every second in the database which can create memory overflows if you try to load a lot of data in the viewer. You can now tell PAMGuard to only load a data point every n seconds which will reduce the number of points loaded. Useful when making large scale overview maps of a survey.
  4. Sound Trap tools module. This is a development module for users of the Ocean Instruments Sound Trap who have it configured to run automatic click detection. This feature is currently in its development phase and is of little relevance to most users.

Bug Fixes

  1. Bug 246. AIS Data Unpacking. Bug in AIS data unpacker fixed.
  2. Bug 247. Fixed Landmark display. Landmarks were not displaying in the viewer. This is now fixed.
  3. Bug 248. Crash in hydrophone array manager. Bug in array manager would crash PAMGuard when the click detector was configured with more channels than the sound acquisition system (almost impossible to achieve, but someone managed it).
  4. Bug 249. Corrected bugs in Rocca analysis of click events.
  5. Bug 250. DIFAR module was crashing if it attempted to triangulate between more than two simultaneous bearings. Fixed.
  6. Bug 251. Fixed error in DIFAR intensity calculation.
  7. Bug 252. Bug which plotted bearings to whistle and moan detections from the front hydrophone rather than the central position between hydrophones now fixed.

 

 

Version 1.13.05 Beta, July 2015

Changes

  1. Improved options for plotting clicks on the map in viewer mode - can now select clicks by the type of event they are part of (when marked as part of an offline event).

Bug Fixes

The following bugs have been fixed for this release.

  1. Bug 231. PAMGuard freezing when starting viewer mode. (Caused by an infinite loop in the map module). Fixed.
  2. Bug 232. Incorrect click length calculation in ROCCA module. Fixed.
  3. Bug 233. ROCCA not analysing correct clicks in Viewer mode. Fixed.
  4. Bug 234. Hydrophone import of .paf files crashing. Fixed.
  5. Bug 235. Target motion analyser crashes when changing default bearing line length. Fixed.
  6. Bug 236. Whistle classifier crashing during batch training just prior to writing results files. Fixed.
  7. Bug 237. Logger forms not saving data to database after sound acquisition starts. Fixed.
  8. Bug 238. Viewer mode out of memory error. Have adjusted memory allocation to allow more memory for the database interface. Hopefully Fixed.
  9. Bug 239. Fixed bug in the DIFAR module that was incorrectly preventing cross-fixes for some calls.

Details of these bugs can be found at https://sourceforge.net/p/pamguard/bugs

Version 1.13.04 Beta, June 2015

Changes

  1. Spectrogram annotation marks. A simple system for marking spectrograms during real time analysis has been incorporated. To use it, add the module, in the spectrogram settings, select the annotation marks in the 'Mark Observers' tab of the spectrogram configuration dialog, and also right click on the spectrogram and select to display the annotations. Annotations are saved to the database so you will also need a database module in your configuration.  
  2. A new system for important warning messages has been implemented. Warnings such as failure to connect to the GPS or a database error will now appear at the top of the main PAMGuard display.
  3. File and Folder audio input systems now have an optional repeat button which is useful when using PAMGuard for demonstration purposes.
  4. The sound File and Folder audio input systems now have an optional time zone setting. Note that PAMGuard analysis should still all be taking place in UTC and that this option is intended to allow the conversion of file times which were not recorded as UTC into UTC and not the other way around. Use the option with caution !
  5. The Open Office Database system has been removed from the list of available options since it is not reliable. If you require a free database solution we recommend you use the MySql Community Server http://dev.mysql.com/downloads/mysql/
  6. Changed Rocca Measurement menu item to open a window containing click events, instead of a submenu listing click events.  Using a window simplifies multiple event selections
  7. The DIFAR module has received numerous improvements and bugfixes after 6 weeks of field testing.

Bug Fixes

The following bugs have been fixed for this release.

  1. Bug 220 Sample counts were wrapping and causing PAMGuard to report incorrect times after 2^31 samples.
  2. Bug 223. Click detector null clicks (This primarily only affected offline file analysis).
  3. Bug 225. Display of remaining recording time. Was only displaying hours, minutes and seconds. Now correctly displays the number of remaining days.
  4. Bug 226. Spectrogram Mark Observer list doesn't refresh when modules added or removed.
  5. Bug 227. Logger forms not working with MySQL. Several minor issues with the MySQL interface generally and in particular with the logger forms module have been resolved.
  6. Bug 228. Occasional crashing when training the whistle classifier.
  7. Bug 229. Fixed bug in Viewer Mode which caused Rocca to crash when analyzing click event containing unclassified clicks
  8. Bug 230. Click Bearing Display. With a two hydrophone system, clicks calculated to have a bearing of exactly 180 degrees would be displayed at 0 degrees on the bearing time display.

 

Details of these bugs can be found at https://sourceforge.net/p/pamguard/bugs

Version 1.13.03 Beta, March 2015

Changes

Small changes have been made to the ROCCA whistle classifier module: Added Sampling Rate, Number of Channels and Geographic Location to the Rocca contour output file.  Number of Channels and Geographic Location can be specified by the user in the Rocca Parameters dialog Notes tab.

Bug Fixes

A number of minor bugs have been fixed for this release.

  1. Bug 209. Map zoom level. This was zoomed right into a range of about 1m when new maps were created. This is now fixed and it starts with a default range of 10km on the display.
  2. Bug 212. Decimator crashed. This only happened very rarely and only if a very large decimation factor was used, so it's unlikely to have affected anyone.
  3. Bug 215. Sound acquisition dialog crashing. Could happen if there were no sound cards installed on a system.
