[Erppcatoolkit-support] EP Toolkit 2.62 released

[Joseph D. <jd...@me...>]

EP Toolkit version 2.62 has been released:
https://sourceforge.net/projects/erppcatoolkit/ <https://sourceforge.net/projects/erppcatoolkit/>

This is mostly a bugfix release focusing on frequency domain analyses, along with a number of small improvements.  The most consequential change is that when combining frequency domain data in all dimensions except channels, the internal representation is converted to absolute amplitude first.  This is discussed further in the tutorial documentation.

Release Notes:

1) Fixed crash when performing time-frequency transform on single-trial data files.  
2) Contrast button of ANOVA pane only presents the between contrast controls if there are more than one between levels.  
3) When performing time-frequency transform on continuous data files, lops off data at ends in increments of one second to that edit epochs still align properly.  
4) Previously would either crash or the edit epochs would end up misaligned by half of the T-F window (which was .5 seconds by default).  
5) Also, since the T-F transform reaches into the adjoining epochs, if they were bad data then the current epoch is also marked as being bad (both for trial and for channels).  
6) Bad data edits passed on to segmented files in segmentation function.  
7) Flexible segments implemented in segmentation function.  
8) Added option to clear working set to File menu.  
8) Fixed crash when segmenting time-frequency data.  
9) Fixed trial names not being correctly numbered when appending trials to a single-trial file using the Edit function, usually resulting in error messages.  
10) Fixed crash when using contrast function.  
11) Added support for averaging multi-file subjects.  
12) Fixed crash when expanding channel of TFT data in View Waves function and not all four colors are being used.  
13) Fixed displaying separate imaginary component of spectral data when the FFT units are not set for complex units.  
14) For TFT data, when View set to display only one Hz bin, switches to waveform display rather than erpimage display.  
15) Supports display of flexible segments.  
16) Fixed View Topos displaying imaginary component of FFT data even if FFT units not specified as being complex.  
17) Improved View Topos auto scaling for dB unit FFT data.  
18) In Show Waves, only EEG chans are subjected to FFT unit conversions.  
19) PCA now drops non-EEG channels and regional EEG channels.  
20) Added support for sample tests for TFT data.  
21) Fixed Window pane crashing when first dataset in working set is not an average file.  
22) Fixed crash when windowing frequency-domain data.  
23) Fixed Window function saves both imaginary and real files for spectral data even when units are not set as complex.  
24) Fixed single-sample duration sampleTest results not displaying in View Waves.  
25) Fixed Window function text file headers not mentioning dB scaling for spectral data.  
26) Scaling input boxes in View pane now allow up to four decimals to better accommodate power units for spectral data.  
27) Fixed not combining trial specs correctly over subjects, resulting in crashes down the line in ANOVA function.  
28) Fixed spectral density conversion incorrectly applied to View pane controls for complex and amplitude scaling, resulting in the numbers being changed from what was input.  
29) Fixed robust ANOVA apparently providing effect size for within contasts of more than two levels when should have been disabled.  
30) Fixed View function's conversion to spectral density dividing by bin width rather than sqrt(bin width).  
31) Fixed View Topos sometimes crashing when frequency band is just one Hz.  
32) Now allows just one sample of TFT data to be chosen for display using the View function.  
33) Improved default auto-scaling for View Waves and View Topos.  
34) When adding together freq data other than channels, switch to amplitude scaling for internal representation.  
35) Fixed crashes in Average function when using median or trimmed means options.  
36) Allow baseline correction to be applied to TFT data.  
37) Improved presentation of TFT erpimages.  
38) Presence of NaN in EEG channels no longer zeroed as bad data if original file was an .ept file (as fix for zeroing out phase-lock transform when there is a flat reference channel).  
39) Improved dragging of red lines in Template Creation pane.  
40) Added Compare Channels option to the View Topos pop-up menu.  
41) Fixed crash in Transform function when filtering continuous data.  
42) Fixed crash that can happen when segmenting continuous data.
