[Erppcatoolkit-support] EP Toolkit 2.87 released

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

EP Toolkit version 2.87 has been released:
https://sourceforge.net/projects/erppcatoolkit/ <https://sourceforge.net/projects/erppcatoolkit/>

This release has an important bugfix for the Edit function treating negative weights as positive when generating difference waves.  Other than that, there are a variety of bugfixes. There is also a new addition of the Extended-Infomax, FastICA, JADE, and SOBI ICA rotations for both the PCA function and the blink correction routine.

1) Fixed crash when using alpha correction, saccade, and EMG correction options in Preprocessing function. 
2) Fixed crash in Average function when Drop Events option not selected. 
3) SampleTest applies test to all channels, not just EEG channels. 
4) Added JADE, SOBI, and fastICA rotations to PCA. 
5) Turned off binICA since it seems to be slower than matlab code even for linux now. 
6) Bad observations are output from PCA and blink correction as NaN rather than zeros. 
7) Added preferences setting to set rotation type for blink correction. 
8) Parallelized channel interpolation when Matlab Distributed Computing Toolbox is installed. 
9) Fixed error when using Alpha correction option in preprocessing and there is a bad EOG channel. 
10) Fixed crash when adding subjects, as in appending. 
11) Fixed crash for PCA of frequency data, including alpha correction option of preprocessing. 
12) Automatically regenerates corrupted EPdataset files. 
13) Fixed when reading mff files, fiducial information not being formatted correctly in the implicit field, resulting in crashes down the line. 
14) Fixed negative weights being treated as positive when adding data together using the Edit function. 
15) Fixed Average function only grand averaging trial specs of last cell of subject average files. 
16) Fixed issues with reinitializing EPeeg RAM cache rather than updating it when updating an existing dataset in the working set. 
17) Fixed crash with COR option of PCA function. 
18) Fixed crash when loading EEGlab .study dataset. 
19) Fixed crash when reading EGI data in .set format due to issues with reading unicode text files. 
20) Made epsilon setting of Geomin rotation controllable via RotOpt input parameter (thanks to Andreas Widmann).

Stay healthy everyone!
