Hi Petr, Can you provide us with some more details? Which version of FreeSurfer are you using and on what platform? Could you attach a copy of the recon-all.log file for one of these cases so we can read the full error reported?

Have you tried looking at the orig.mgz which is generated prior to the mri_nu_correct.mni step to see if it looks reasonable? -Louis

Dear members,

when I run recon_all -subjid name -autorecon1 process stops with ERROR at nu_correct. This happens for DICOM but also IMA file type. I tried several brains. Do you have any idea what is wrong?

Thanks much, Petr Zach
