[Erppcatoolkit-support] EP Toolkit 2.79 released

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

EP Toolkit version 2.79 has been released:
https://sourceforge.net/projects/erppcatoolkit/ <https://sourceforge.net/projects/erppcatoolkit/>

Aside from the usual bug fixes, have added some improvements to the View Topos mode and its controls.  Also improved speed of functions somewhat by caching EEG data in RAM for those with computers with enough memory.  Also added a status button that indicates when the Toolkit is processing and can abort functions and reset its status when pressed.  The compiled mex code for the robust ANOVAs was unintentionally turned off in recent releases and has been turned back on for six-fold improvement in speed.  Also it now uses a pseudo-inverse for calculations, which allows it to better handle singularity.

1) Fixed crash when the -all- option is used and then the dataset is changed and is then viewed with View Topos. 
2) Fix EPheader option can also fix missing EP headers. 
3) Fixed crash in View Topos when using fixed min and max voltages. 
4) Fixed crash in View Waves when plotting sampleTest results without waveforms. 
5) Added popupmenu to View Topos to change range to symmetrical numbers. 
6) Changed View Topo’s time mode so that every sample is displayed rather than just every 50 ms. 
7) Updated dipole analysis so it continues to work with current versions of FieldTrip. 
8) Fixed crash in Edit function after adding combined cell and then deleting cells. 
9) Topos page controls now labeled by row label rather than page number. 
10) Fixed crash when conducting second or third step PCA on PCA data from prior to version 2.76. 
11) Added EP reset button to upper right corner. 
12) Fixed case where a previous error leaves behind a copy of the temporary CED file, resulting in errors when trying to read a new CED file. 
13) Fixed case where user does not have write permission for Matlab active directory, resulting in failure to read the CED file. 
14) Fixed crash in saccade correction step of Preprocessing function when data have no events. 
15) No longer maintains noise and std information when combining subjects in factor data as not really needed and requires substantial memory space. 
16) Finally figured out why Matlab was sometimes leaving out GUI controls even with the drawnow command. 
17) Now maintains a copy of the most recent datasets from the active set in RAM to minimize disk access time. 
18) Fixed Greek letter mu garbled in some figure labels. 
19) Fixed crash when conducting sample test and there are cells listed after sample test cells. 
20) Fixed case in movement correction module of Preprocessing function where channel has sporadic high amplitude bad data, derailing mean correction. 
21) Accelerates artifact correction by adding option to keep chunks in RAM. 
22) Added subplots for global bad channels to Preprocessing function summary plots. 
23) In preprocessing function, global bad channel detection now based on baselined/detrended copy of data. 
24) Fixed not using trial specs when resegmenting single-trial data. 
25) Restored compiled functions for robust ANOVAs, which was turned off in version 2.72 (oops). 
26) Improved default setting behavior of the View controls. 
27) Changed, in robust ANOVA code, inv calls to pinv to better handle singular and near-singular data. 
28) Fixed crash when saving averaged data in text format. 
29) Fixed crash when chunking single-trial or averaged data.
