Hi Shahar

Can you look at the input to that step? Usually it means something prior has gone wrong (like the skull stripping remove the entire brain or something). And maybe post a couple of images of the processing (the orig.mgz, the T1.mgz, the brainmask.mgz, …)

Cheers Bruce

External Email - Use Caution Dear freesurfer team,

I am attempting to use freesurfer using fmriprep but I get the following error message:

error: No such file or directory error: MRInormFindControlPoints: could not find enough control points error: No such file or directory error: MRInormFindControlPoints failed

I've searched the archive but couldn't find a solution. Does anyone have any thoughts on how to trouble-shoot this one?

Also, I've attached the recon-all.log in case it's of any use.
