Thanks doug. Also, Please can you verify if this are the right codes for performing ROI surface based analysis using the command line. I tried to reverse the whole brain analysis tutorial with some of the previous threads i read. I'm trying to mask the entorhinal and MT and then perform ROI on them using GLM. Thanks a lot

I think there is an example on the wiki in the ROI analysis section. See

After you run aparcstats2table, you can run mri_glmfit with --table aparcstatstable instead of --y. The output folder will have tables with lists of ROIs and p-values

Hey FreeSurfer experts, Does anyone know the steps i have to perform if I want to conduct surface based thickness analysis using GLM but with ROI approach. Thank you very much. Best, Paul
