[Erppcatoolkit-support] EP Toolkit 2.89 released

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

EP Toolkit version 2.89 has been released:

Okay, I'm an idiot. Actually 2.86 and 2.87 were fine. I just forgot I had done some convoluted programming to try to reduce memory usage. So my attempted fix for a non-problem in 2.88 was the actual bug. This is all now fixed with 2.89. I'm adding some additional checks to my test script to preclude this sort of thing in the future.

Otherwise, I made some minor improvements in the factor score computation routines and added a mains noise correction option to the Preprocessing function (incorporating the one made available through the PREP Pipeline).

I’m making continued improvements to the Preprocessing Function in support of a methods paper I’m writing.

Stay healthy everyone!

1) Made further improvements to PTB file format support. 
2) Fixed crash in Average function when task names used in segmentation. 
3) Fixed sometimes crashing when trying to generate the legend in View Waves figure. 
4) Fixed assumption that channel names derived from hdr.labels is a column-vector, resulting in failure to read when they are not. 
5) Added mains noise correction to preprocessing function. 
6) Fixed crash when combining subjects into a grand average and there are task specs. 
7) Modified auto-alignment of electrode coordinates to work with EGI montages even when the fiducial locations are missing. 
8) Improved the factor score computation for PCA and ICA rotations. 
9) Fixed minor factor score computation bug added in 2.88.
