Hi FreeSurfer Gurus,

I recently moved from using a linux-based FreeSurfer to one of the newer Darwin distributions. I've been following the tutorial at http://surfer.nmr.mgh.harvard.edu/docs/ftp/pub/docs/fsTutorial/morphAndRecon..., but my cortical reconstruction was failing on -autorecon2 with the following error:

--------------------------------------------- Intensity Normalization2 Thu Jul 14 23:51:48 PDT 2005 /Volumes/Storage/data/freesurfer/subjects/clda/mri mri_normalize -mask brain nu.mgz T1.mgz reading from nu.mgz... corRead(): can't open file /Volumes/Storage/data/freesurfer/subjects/clda/mri/brain/COR-.info mri_normalize: could not open mask volume brain.

using MR volume brain to mask input volume... ERROR: mri_normalize exited with non-zero status recon-all exited with errors at Thu Jul 14 23:51:54 PDT 2005

=============================================

So I installed a newer recon-all from Doug's outgoing ftp directory (timestamp 7/26/05) that Russ Poldrack recommended. This one crashed (seg fault) after initial inflation, during topology correction, I think.

I have attached a copy of the most recent log file. I am running panther on a G5 with two 2.5 GHz CPUs and 4 GB of memory. Please let me know what other information you might need.

Thanks for any advice, Colleen Tuffy Human Neuroimaging Lab University of Oregon
