You can create a surface overlay in matlab and display it using freeview.  See https://gate.nmr.mgh.harvard.edu/safelinks/greve/annotval2surfoverlay.m To read it into matlab, you can run pcc = MRIread('pcc.mgh');

You can convert it to text with mri_convert --ascii pcc.mgh outputtextfile

External Email - Use Caution

Hello FreeSurfer Users,

I want to run an ROI-based analysis on mri_glmfit as opposed to vertex-based. I know that if I run mri_glmfit with the --table flag and give it the output of asegstats2table or aparcstats2table, it will run the analysis on the ROIs and output tables showing significance. In each contrast directory that was created from mri_glmfit, I see there is a pcc.mgh. Is there any way to display this on the surface or put it into a table format?

Mahalo,
