Hi, we've run into an issue running FS 4.01 on an Altix cluster (SuSE Itanium distribution - freesurfer-ia64-unknown-linux-gnu-stable4-20070918). On some subjects mri_cc falls over with a segmentation fault error (output pasted below).

Running mri_cc -aseg aseg.auto.mgz -o aseg.auto_CCseg.mgz subject_id on the same subject on a different machine (Mac OS X) works ok.

If we run mri_cc (on a subject that worked on the Altix) on our other machine we get identical output in recon-all.log. It seems strange that it works on some subjects and not on others. Any ideas as to what's going on? Please let me know if I need to provide any further information.

Thanks Heath
