Do you want to do it on a voxel-wise (map) basis? I guess you could just run
mri_concat subj1/lesionmap.mni152.mgz subj2/lesionmap.mni152.mgz ...
subjN/lesionmap.mni152.mgz --o stack.lesionmaps.mgz
Then run a voxel-wise GLM on the stack. This tricky. You'll probably
want to smooth it some (mri_fwhm). When you run mri_glmfit make sure to
add --no-prune. You should also use permutation when you do correction
for multiple comparisons (mri_glmfit-sim)

Thanks Douglas, "mri_convert lesionmap.mgz -at samseg.m3z
lesionmap.mni152.mgz" worked fabulously after some tweaks in the
command line!
What would be the best approach to compare population-wise lesion heat
maps between groups of subjects using the output from SAMSEG? (the
full FS pipeline cannot process my data due to brain defects and time
restrictions).
Thanks for all the support for these fantastic tools!
Stay safe!
