Hi @Samiee,
I am on the latest version of brainstorm and I am still having the same issues.
Under tPAC -> surrogate tPAC is still greyed out. And extracting comodulogram doesn't work either. It produces the error that I have posted above.
For all these operations I am using tPAC: ROI (Full) matrix as input (over multiple trials and subjects). Any help would be highly appreciated.
I am running BST on a Centos server.
Edit: When I run the average tPAC under basic analysis of tPAC maps. The output is a mean tPAC for every participant for every trial, instead of one representative tPAC map across the whole group.
