The ribbon volume needs to have labels like the FreeSurfer ribbon volume (i.e. the specific numbers for grey matter). Also, what is your commandline?
Peace, Matt. _____ From: caret-users-boun...@brainvis.wustl.edu [mailto:caret-users-boun...@brainvis.wustl.edu] On Behalf Of Colin Reveley Sent: Wednesday, July 04, 2012 10:39 AM To: caret-users@brainvis.wustl.edu Subject: Re: [caret-users] myelin forgot 4th july... tried a few more things: make all vols -++ (FSL style) put MTR into intensity range of t1/t2 as described in matt's paper (no dice). then, add one to that mtr and use a vol of all ones as "t2" so divide by zero is impossible, ever. (no dice) take that mtr from previous step, square it, use the squared as "t1" and the original as "t2" always the same as prev mail. the t1/t2 output vol is blank. it should be my mtr input. maybe it does need to be 1mm? don't see why.
