Version 4.0.3-beta

Bugs and issues fixed

• Normalized feature values of NaN now equal to 0. NaN values may be generated when both min and max values of a feature are 0.

• Fixed a hard coded variable in features computation.

• Fixed the Labelling Quality procedure which was causing an error upon execution.

• Fixed an issue with the agreement matrix where the numbers were generated into wrong positions.

• Updated code for the Demo procedure.

Version 4.0.2-beta

• Fixed a bug when generating statistics
• Fixed some MAC compatibility issues

Version 4.0.1-beta

Major Changes

A number of new functionalities are available:

• Ability to label whole trajectories
• Ability to turn non-segmented trajectories into segments
• Ability to add custom class tags
• Ability to load custom computed trajectory features
• More analysis results including confidence intervals and classification statistics.
• Raw classification results are now exported for further custom analysis (or in case the Friedman test cannot be performed).

Minor Changes

• Fixed axes labels and file names.
• Better figure graphics.
• Some parts of the code have been re-written.
• Ability to read UTF16LE txt files.

Bugs and issues fixed

• New more robust classification methodology (see issue).

Version 3.1-beta

Synopsis

Major Changes

• Improved and more generalized formula for mapping segment classes to trajectories (see Gehring, Tiago V., et al. supplementary material 1.6)
• More statistics can now be computed about the classification quality and agreement of the classifiers after the majority voting merging (see wiki Class Statistics).

Minor Changes

• Browse Trajectory Data now contains a counter for the labels provided.

Known Issues

• Sometimes the user may need to press the buttons of the main GUI two times.
• The MAC release does not include the console window.
• The MAC release cannot read and parse EXCEL files. Users are advised to use TXT and CSV file format on MACs.

Version 3.1.0-test

This is a test release of version 3.1.0. Only the source code (MATLAB) is provided.

Version 3.0-beta

Major Changes

• Redesigned software and code.
• Updated classification procedure.
• New graphical user interface which includes an updated way of parsing info from exported Ethovision files.
• All the results are extracted as CSV files
• Both Windows and MAC installer.

Minor Changes

• Trajectory track: full file name is used as the track.
• All the generated CSV files have headers.

Known Issues

• Sometimes the user may need to press the buttons of the main GUI two times.
• The MAC release does not include the console window.
• The MAC release cannot read and parse EXCEL files. Users are advised to use TXT and CSV file format on MACs.

Version 2.0-beta

Major Changes

• The program can now read TXT files apart from XLSX and CSV.
• The user now has the ability to specify the generated figures' properties (font, text size, line width) and the figures' export format.
• Both Windows and MAC installer.

Minor Changes

• Some more Waitbars are added.
• p-values, confusion matrix and transition probabilities are now exported automatically to a TXT files.

Known Issues

• The MAC release does not include the console window. The user needs to see the generated text files for the numerical values (p-values, confusion matrix, transition probabilities).
• The MAC release cannot read and parse EXCEL files. Users are advised to use TXT and CSV file format on MACs.

Initial Update

Still in beta testing.

Major Changes:

• The program can now read XLSX files apart from CSV.
• Number of Clusters can now be identified with the help of a small GUI.

Minor Changes:

• The segmentation objects can now be transferred and loaded to any machine (the user may be asked to change the output folder).
• Waitbars are introduced and appear during specific processing stages (data parsing and feature computation) to indicate that the program is busy. During these stages the main GUI become invisible.
• Error messages are more detailed.

Initial Release

Still in beta testing.
