Hi Tobias

yes, mris_calc should do it. If you give the output extension .mgz it will save in that format instead of curv I believe (and will work fine as an overlay)

cheers

Hi, 
Is there a way to subtract one surface overlay from another (for example in
fsaverage) and still having the output being an .mgh overlay file? 
I saw that mis_calc does a similar procedure but automatically outputs the result
as out.mgz. 
Thank you for the help! 
Kind regards,
Tobias
