[Erppcatoolkit-support] EP Toolkit 2.97 released

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

EP Toolkit version 2.97 has been released:
https://sourceforge.net/projects/erppcatoolkit/ <https://sourceforge.net/projects/erppcatoolkit/>

This release was mostly about fixing bugs and adding various minor refinements.  The EGI CED files have been updated to reflect the current age-specific electrode coordinate .sfp files provided by EGI.

1) Fixed crash when combining subjects, as in a grand average, and the optional standard deviation information is present. 
2) Fixed crash when combining cells and none are good and there are trial specs present. 
3) Fixed crash when reading .ept files where eloc is missing and ced is specified and the file is a spatial PCA file. 
4) Fixed ANOVA function crashing when there are more than two between-group factors. 
5) Fixed crash when there is a BAD channel specified in the CED file. 
6) Fixed regional channels treated as being BAD channels in cases where non .ept file formats are read in. 
7) Fixed crash when merging files, as in Single File Mode, while applying a CED file with BAD channels. 
8) ChanTypes in .fif files are now ignored as they are apparently specified by users rather than being standardized. Instead CED files will need to be used. 
9) Will now accommodate case where .fif file erroneously codes the EOG channels as being fiducial points. 
10) Added .ced file for EGI Hydrocel-33. 
11) Fixed crash in View Waves when there is only one channel with coordinates. 
12) In View Waves, if there is at least one channel with coordinates and there are too many channels with no coordinates to fit on the left side of the figure, will now space them out in columns. 
13) Fixed crash when reading a file and two REF channels are specified in the CED file. 
14) When reading a text file such as a CED file, empty lines are ignored. 
15) Added support for reading sfp files in Overview pane of Edit function. 
16) Fixed crash when combining subjects and there are empty trial spec values, as when generating a PCA file. 
17) Added support for reading writing Matlab .mat files. 
18) Fixed crash when reading file with empty array as trial specs field. 
19) Fixed crash in Edit function when renaming an implicit channel. 
20) Fixed crash in Edit function when plotting electrode positions with the Head button and there is a fiducial with the name of Nz or T9 or T10. 
21) Fixed weights in Edit function not being reinitialized after deleting channels. 
22) Updated code for recognizing alternate names for EGI reference channel so that it is not added when electrode coordinates are being added if under a different name. 
23) When transforming electrodes to canonical coordinates (as in 3D heads and source analyses), now relies on fiducials plus Cz (plus any other channel name matches) for EGI montages and only uses approximate channel matches if they are not available. 
24) Fixed names of fiducial channels not being included when saving a CED file using the Channels Pane of the Edit function. 
25) Updated the EGI Hydrocel CED files to the current versions. 
26) Added ability to load and save ANOVA table settings and auto ANOVA table button. 
27) Fixed crash when reading a _evt.txt file where there is a header but no data. 
28) Added T in front of variable names when writing a file in stacked format. 
29) When reading in data files, fixed not properly matching up CED with data channels when some of the channel names do not match and at least one of them was a BAD channel. 
30) Names that readlocs reserves for fiducials ('nz' 'lpa' 'rpa' 'nasion' 'left' 'right' 'nazion' 'fidnz' 'fidt9' 'fidt10' 'cms' 'drl' 'nas' 'lht' 'rht' 'lhj' 'rhj') may now be used as channel names. 
31) Fixed crash in blink correction step of preprocess function when sampling rate higher than 1000. 
32) Added option to run either SAS or SPSS version of Promax algorithm. 
33) Turning off the figure labels now also turns off the axis labels in the expanded channel figures.

Note that you will need to update your copy of FieldTrip to a 2021 version or later to be able to read EEGlab files created with version 2021.0 onwards. Also remember to click on Set Path when updating the EP Toolkit and use the "Add with Subfolders" button. I've also made a fix to the FieldTrip's I/O code, which the EP Toolkit uses for reading .fif files that can causes crashes under certain conditions, but they haven't gotten around to incorporating it into the codebase. You can download the fixed file from FieldTrip's github site or write me if you need it, but keep in mind that if the EP Toolkit is not crashing when you read your .fif files, you don't need it.
