Hi Tali
can you email me the nu.mgz, the talairach.lta and the brainmask.mgz? I'll see if I can get it to happen and fix it.
thanks Bruce

Hi all,
I was having consistent errors with two cases during mri_ca_normalize, and after using an updated version (mri_ca_normalize_centos), one case went through smoothly. I'm having trouble with the second case, however; it now repeatedly reports a segmentation fault partway through mri_ca_normalize (error message below) - any ideas??
Thanks! Tali Swisher
