Hi,
I would like to perfom PPI analysis to my data, but I am not sure if what I have done so far is correct. I do have several questions.
1. In one of my experiments I would like to observe the interaction of brain regions (ie. Parietal) during a task, between two different groups.
I have performed PPI on the individual data, but I am not sure how to proceed to do the comparison. Shall I do a t-test using the ppi.mat that I got from each subject?
2. In my second experiment, one of the groups did the same task under another condition. I would like to check for the changes of for example parietal when comparing to the first session. Furthermore I would like to compare these changes with the second group. Here, should I use gPPI?
In conclusion my main doubt is that I do not know how to do the group level statistics
I appreciate the help,
Regards,
Olga LucĂa
