That number is in voxels or vertices. If you want surface area, then use mri_segstats something like

mri_segstats --i $SUBJECTS_DIR/fsaverage/surf/lh.white.avg.area.mgh --seg glmdir/mask.mgh --id 1 --accumulate --sum sum.dat

Hello,

When running the Clusterwise Correction for Multiple Comparisons, I used a label as a mask to restrict search area. I want to find out the size of that label, so I guess I can pull that information out from the "mri_glmfit.log", specifically under 'searchspace'? Also I only see a numerical value there, I assume it is in mm2?

Thanks.

Jeni
