How to do statistical analysis(e.g.,t test,ANOVA) with brain connectivity matrix in Brainstrom?

Dear experts,

Recently, I used brainstorm to create whole brain connectivity matrices by phase transfer entropy in grand average EEG data of both experimental and control groups.I defined 68 scouts/nodes(Fig.1), so I got a 68*68 matrix/edges(Fig.2). Then I wanted to do statistical analysis(e.g., t test,ANOVA) to find which regions have significant stronger connectivity in experimental group than control group.But I do not know how to do that in brainstorm?
I tried to put two files(from experimental and control group,respectively) in Process2,but it could not work(Fig.3).Could you tell me how to do statistical analysis in the described circumstances?
Many thanks!2

For any type of statistical analysis, you need multiple samples of each condition.
You need to place multiple files in the two lists of files (ie. one file A and B for each subject, or each trial)

Thanks for your advice!
