Hi Fred

if you upload the data I'll take a look, although I don't think a bunch of steps will work properly with .75mm data. Usually we resample to 1mm, then recon and run a post-hoc surface deformation to match the .75mm data cheers Bruce

Dear all

I have been trying to recon a high-res (.75 isotropic) volume, which goes along fine until it hits a certain bit of mri_ca_normalize. I've run this 4 times and it always dies at the same point.

There was also a previous unanswered post about 8 months ago showing an error at the same place

## Recon-all command: recon-all -all -cm -subjid dancar-750um2

# I checked the Talairach transform, which was OK.

## The mri_ca_normalize command as run by recon-all
