The white matter surface creation step resulted in a poor L/R hemisphere separation in one of my subjects.  A portion of the cut is shifted into the left hemisphere white matter (running from the corpus callosum downward to the brain stem).  To remedy this I ran the following command to manually set the corpus callosum cutting planes:

recon-all –subjid pbb_subj.07 –fill –cc-xyz 131 125 146

I encountered the following error:

Searching for cutting planes…Segmentation fault (core dumped).

Can you offer me any advice on how to remedy this problem?

Thanks,

Jason
