Hello FreeSurfer Developers,
I attempted to run recon-all in cerebellum hypo case, but it resulted in an error. The message indicated “trgvtxno = -1 < 0.” When I inspected the data in Freeview, I noticed that the left and right white matter and pial surfaces were intersecting near the corpus callosum. Therefore, I mannually removed the white matter around the corpus callosum in wm.mgz and reran recon-all -autorecon2-wm -autorecon3 -subjid <subject>. However, the same error continues to occur, and left and right surface isn't separated. (https://secure-web.cisco.com/1C9t-jL1GVEMftdXHKe19QFSQcOKzZdZalLfUD3e4RKaX6i...)
I've searched the list and no similar errors have been reported. Does anyone have any thoughts on how to trouble-shoot this one? Also, Ive attached the recon-all.log in case it's of any use.
