[Freesurfer] Segmentation fault?

Hi all,

I am running recon-all as follows:

recon-all -subjid subj1 -all

and (after about 4 hours of running,) get this error:

0516: dt=0.000000, rms=0.507 (0.000%), neg=0, invalid=766 Segmentation fault ERROR: mri_ca_register with non-zero status 139 but continuing despite the error #-------------------------------------- #@# CA Reg Inv Sat Feb 6 02:56:03 EST 2010 /usr/local/freesurfer/subjects/be496/mri

mri_ca_register -invert-and-save transforms/talairach.m3z

Loading, Inverting, Saving, Exiting ... Reading transforms/talairach.m3z ERROR: cannot find or read transforms/talairach.m3z ERROR: mri_ca_register with non-zero status 0

It seems that perhaps this is because it cannot find "transforms/talairach.m3z" - indeed, this file doesn't exist. But should this be something generated by recon-all? Should I be running recon-all differently?

Thanks for your help,

Raghav
