Ooops sorry for the delay.
I can send you a file if you want to play with it (dsf from BrainSuite).
But we went ahead and installed freesurfer. I misspoke regarding FSL.
The support, options, capabilities, etc all seem to be better with freesurfer.
We have a 12-core OS-X behemoth on the way. :) Closest we are going to get to a cluster.
One hopes it will be a bit faster. I would prefer MP compiling like I just did with AFNI - which likely will never really need to use more than a core or two - may look into that.
Cheers,
JP
