[Erppcatoolkit-support] EP Toolkit 2.65 released

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

EP Toolkit version 2.65 has been released:
https://sourceforge.net/projects/erppcatoolkit/ <https://sourceforge.net/projects/erppcatoolkit/>

This was mostly a bugfix release focusing on preprocessing and the view functions.  An experimental alpha correction option has been added to preprocessing, although it is a memory hog and can crash the computer.  global field power and error band options have been added to the View function.

1) Fixed part of file name after a period when writing out non-EGIS files.
2) Fixed crash in blink correction when chunking and there are events.
3) Fixed crash when preprocessing data containing impedance values.
4) Fixed crash when preprocessing multi-subject average files.
5) Fixed crash when input file has impedances field and channels are being added but none are being added to the impedances field.
6) Fixed crash when averaging data containing impedance values.
7) Fixed boundary events not being handled correctly in BrainVision eeg files.
8) Fixed odd behavior in Read files and Average functions due to Matlab bug in which str2num executes word strings which are function names like "web”.  
9) Fixed saccade potential preprocessing crashing when channels marked as being missing in preprocessing preferences with a -1.
10) Fixed crash in blink correction when 1000 is not evenly divisible by the sampling rate.
11) Fixed crash in preprocessing function when there is an event with an empty .value field.
12) Fixed crash when combining cells and the data is frequency-domain, as when conducting PCA on frequency-domain data.
13) Fixed bugs causing saccade potential to not work as effectively for single-trial data.
14) EMG correction rereferences to Cz to standardize procedure and then restores original reference afterwards.
15) EMG correction  adds an EMG channel to record mean absolute EMG activity removed by the procedure.
16) Fixed crash in blink correction when sample length (e.g., 4ms for 250Hz) did not divide evenly into 100 ms.
17) Fixed crash in saccade correction when no good samples in an epoch.
18) Added an experimental alpha correction option to preprocessing function.  
19) Fixed crash in preprocessing when chunking single-trial data.
20) Added global field power and error band options to the View Waves function.
21) Fixed crash when displaying -all- trials in View Waves function.

To read BrainVision impedances, need at least FieldTrip20171207.
