Hi all, I also had this same problem with -T2pial, posted on the archives back in March. I, too, have a log where mri_convert is given an input of ERROR: could not determine file for ..., and I believe I've traced it back to this early line in bbregister (our copy is dated at 2/23/2013,

[Freesurfer] T2pial's use of bbregister failing

Hi all, Congrats on the new version! I've been excited to see how the use of data from T2 images could help pial surface estimation, but I'm encountering a problem with getting that to work. It seems to be failing to properly execute the bbregister command built into this part of the new

Hi, I have a few questions about the process flow for the last stable build (5.0.0). After looking over http://surfer.nmr.mgh.harvard.edu/fswiki/recon-all , https://surfer.nmr.mgh.harvard.edu/fswiki/ReconAllDevTable , and http://surfer.nmr.mgh.harvard.edu/fswiki/OtherUsefulFlags , it looks
