Hello All,

I'm getting an error similar to another some months back.
http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg09729.html

The command is failing on 2 of our subjects, but running properly for
others. For the 2 failed sessions, it's creating only the dof and Xtmp.mat
files in the analysis directory. I have pasted the ending output below.
Any input on how to resolve this is appreciated. Thanks!
