Hi,

We have previously run recon-all -all on 72 subjects using Freesurfer v. 4.01. After routine edits we reprocessed the subjects.

I now want to run the scans again using the updated FS v. 4.05 using the recon-all -all command. We want to have them processed in the latest version in order to do longitudinal analyses.

However, when I run the v. 4.01-processed scans again, using v.4.05 I get the following error in the normalization2 part of the autorecon2 step:

#@# Intensity Normalization2 Fri Oct 10 22:10:06 CEST 2008 /work/1531087.undefined.d/2003A/mri

The same error occurs for all subjects. The error only occurs when I run the subjects on our computing cluster. I have tried to run a couple of scans on a local machine, using the same version. Running locally, I don't get the same error.

We use centOS4 64bit. Any suggestions on how to solve this?

Thanks !
