[Erppcatoolkit-support] EP Toolkit 2.92 released

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

EP Toolkit version 2.92 has been released:
https://sourceforge.net/projects/erppcatoolkit/ <https://sourceforge.net/projects/erppcatoolkit/>

This is mostly a bugfix release, with various minor refinements.  The most helpful upgrade is the addition of a “stacked” text file format, which allows the use of just a single data file for text.  Note that Matlab 2018b or later is now required.  There are still some issues with older EGI montages (pre hydrocel) that I’ll need to work out for the next release.  I also plan to start work on upgrading the logging and scripting capabilities.

Stay healthy everyone!

1) Can omit channel label in waveform figures by setting label size preference setting to zero. 
2) Fixed not having separate preference settings for figure markings and the line widths settings were not having any effect. 
3) Fixed sometimes crashing when trying to read an EGI data file. 
4) Fixed crash when reading in ced file with BAD channels. 
5) Moved option to fix mains noise from Preprocess function to Transform function and added preferences setting. 
6) May now resize the Edit Window. 
7) Fixed error bands not working in View Waves when there are NaN values. 
8) In Average function, fixed covAVE trial-level standard deviation calculation failing to exclude NaN values. 
9) Calculations involving trial-level standard deviation information, like rereference and grand averaging, now correctly excluding NaN values. 
10) May now click on the legend in Show Waves to edit the names. 
11) Added stacked text format to options for reading and writing data files. 
12) Eliminated legacy 'factors' file type from Read function. 
13) PCA data can now be represented without factor vector compression. 
14) Fixed crashing on start up after installation for certain cases. 
15) Actually fixed crash when using the "grand" button of Edit>Subjects subpane and there are missing values in the selected column. 
16) Fixed problems after using all eight colors to display factor results. 
17) Added additional safeguards for initial EPwork setup. 
18) During reading a file, disabled automatic correction of file type to "continuous" from "single-trial" if there is only one trial. 
19) Resamples the data via interpolation if the time points of the data going into an averaged or merged or appended file are not the same rather than just aborting the operation. 
20) Added option to resample data to any arbitrary sampling rate on Samples subpane of Edit function. 
21) In Segment function, for fractional event times, timeshifts the segments via interpolation so that the start of the epoch exactly corresponds to the event time. 
22) Fixed single-trial windowed output sometimes set to zero rather than missing data number for bad data trials.


EP Toolkit now requires Matlab version 2018b or later.
