External Email - Use Caution        

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 gaps in terms of command parameters:

1) mri_binarize lh aparc --min LABEL/NUMBER_OF_SUPRAMARG? --o roimask.mgh

2) fslmaths sig.mgh mult roimask.mgh -o maskedsig.mgh

3) which command could I use to obtain the MNI coordinates of the peak value in maskedsig.mgh?

Thanks a lot in advance!
