Thank you.
Unfortunately, I am not able to provide much more information than this, as I was in the lab for just a limited amount of time and followed some established procedures, so I am not extremely familiar with these matters, and I should probably ask others about this.
I did know of the resources you linked, especially the second one, which I have already used. I was just wondering whether I was missing something obvious as I was trying to move to Brainstorm for this analysis, but I guess there might not be a very straightforward way of implementing all the required information because of how it was acquired.
