Dear all,
Given a series of fsaverage-registered rCBF maps, I am trying to extract the average rCBF value from one specific region. This region, which was a significant cluster from a volumetric (fsl) analysis, was binarized and then converted to surface.
When I run mri_segstats with the --avgwf I obtain two columns. Can you please remind me which one is the average extracted from that ROI, and what is the other column?
Thanks! Marco
