You'll see the header has quite a lot of detritus. best Colin On 22 August 2013 22:24, Colin Reveley <[email protected]> wrote: > hi. > > we have a system (a bespoke system) for non-linear registration of volumes. > > we wondered if we could take the output transform and use that data to shift > the vertices of a surf.gii so that it's transformed. > > much like wb_command and fnirt. > > we tried it. in matlab (using gifti lib) it works. > > unfortunately the resulting surface renders in matlab, but when saved not in > caret or workbench. > > there are a million reasons why that could be.
