Hi Nuria,
yes it's fine, as long as you have determined which ROI to use *before* obtaining your whole-brain results...
Cheers,
Gwenaëlle

Hello,
I performed a longitudinal whole brain VBM analysis using Douaud et al 2009 protocol. In order to test a hypothesis, now I would like to perform a ROI analysis. Would it be correct to perform it using this longitudinal pre-processing for VBM? I did not find any paper about this issue
Thanks a lot,
Núria
