Hi there!
I just updated BS and I saw a new connectivity feature: Envelope Correlation 2020, I tried but I got the next error message:

** Error: [process_henv1n] Connectivity > Envelope Correlation NxN (2020)
** Line 135: Index exceeds matrix dimensions.
**
** Call stack:
** >bst_henv.m at 135

I was trying to compute Envelope 2020 on epoched data (imported in database), 1.5 seg each epoch. I selected these parameters:

connect1366×647 108 KB

I also tried with Morlet Wavelet and I got the same

Maybe I'm doing something wrong

Thanks in advance!

ps: where can I find out some documentation about his measure?
:D!

This new process was not working with the option "All file" selected, indeed.
I fixed this bug in the following commit: https://github.com/brainstorm-tools/brainstorm3/commit/95d618e7a6ccab44d730ff2d1f4737ac7edacf82
Update Brainstorm to get the fix.
Thanks for reporting!

This process will be documented in the new tutorial about connectivity:
https://neuroimage.usc.edu/brainstorm/Tutorials/Connectivity

@hossein27en Could you tell us when we can expect this documentation to be ready?
