Hmmmm, if you send us the data we will take a look. Just the inputs to mri_normalize should do it for this case Cheers Bruce

External Email - Use Caution Hi Bruce,

The nu.mgz input into mri_normalize looks ok to me (screenshot attached), as does the talairach registration.

External Email - Use Caution Hello all,

I am trying to run recon-all on MP2RAGE data from Philips and it exits with errors at this point: 3d normalization pass 1 of 2 error: No such file or directory error: MRInormFindControlPoints: could not find enough control points error: No such file or directory error: MRInormFindControlPoints failed Command exited with non-zero status 253

The log file is attached. The input file was the MPRAGE generated on the scanner console (i.e. not the T1 map). I attached a screenshot of orig.mgz viewed in fsleyes. Any thoughts?

Thanks!

Corinna
