Grand average and statistic analysis of TF map (without scout) between subjects

Hello,

I'm analyzing MEG data and calculating TF map (without scout). I just have 1 condition for every subject.

I'm wondering whether I can do the grand average or statistic analysis (against baseline) of TF map (without scouts) between subjects.

I've already calculated the TF map of each trial of each run for every subject. I guess I cannot directly calculate the grand average or do the statistic analysis because TF map is calculated based on recordings.

So, can I project the TF map (after averaging the TF map of each trial for each subject) on a template, and then do the grand average or statistic analysis?

Yes, that is the way to do so. Check this section on the OMEGA tutorial :
