If you know the vertex number, then you can get the RAS in "tkregister
space", eg, in freeview (other ways too), then use #2 on that page

I can identify the vertex number with highest significance within a ROI in
a surface sig.mgh map (see attached txt). However I don't know how to
compute the corresponding MNI coo
Use mri_annotation2label to convert the, eg, ?h.aparc.annot to a
segmentation (--seg output), then use mri_binarize with 1031.

What do you mean you are trying to overlay it on lh.inflated? the output
of mri_binarize will be a volume, so you'd have to sample it onto the
surface in some way

Just a follow-up, I got stuck at trying to obtain a mask from binarizing a
specific ROI from the aparc+aseg.mgz, aiming to mask my sig.mgh with this
ROI.If for instance, I'd like to create a ROI from the left supramarginal
gyrus, I found that its label

Thanks a lot!
I read the mri_volcluster doc, can you confirm that the TalX TalY TalZ
coordinates are those of the vertex with maximum intensity within the
cluster? (it could be those of the cluster's center of gravity)
Finally, I would be very gratefu
Try mri_volcluster. Pass you masked sig as the input and set --thmin
0.0001 and specify a summary file with --sum. I think that should work

Dear FS experts,
I have a rather simple question:
I would like to obtain the MNI coordinates of the most significant vertex
in a sig.mgh map but within a specific ROI (for instance the left
supramarginal region).
Here is my attempt but with practical
