Hello,

I am attempting to measure the gray matter volume (mm^3) of the insula. After getting all of my labels, I performed the following operations to merge the insula labels before computing the stats:

mri_annotation2label  --subject progr_120544 --hemi lh --outdir ./location
mri_annotation2label  --subject progr_120544 --hemi rh --outdir ./location

mri_mergelabels -i lh.insula.label -i rh.insula.label -o insula

>From here, I'd like to get the volume of the insula for the entire brain and not just in a specific hemisphere. When I looked at the mris_anatomical_stats command, it requires one to specify which hemisphere does the label contain to. However, the mri_mergelabels command merges both hemispheres. I am not sure where to go from here and seek advice.

Thank you,

Mohanad
