Hi- I'm at a bit of a loss as to how to address and/or fix these errors.
The native input images are very good quality; the conversion to T1.mgz is fine; the brainmask.mgz is good, a bit of dura remained at the parietal/occipital region (very common); otherwise, the skull stripping is very clean. The recon-all "finished" but with errors as expected. Processing "continued" to the end, but there is no output except in /mri and /touch. Doing: #@# Skull Stripping First under "Computing MAP estimate using 3481 samples..." IFLAG= -1 LINE SEARCH FAILED.
