It is not really something that can be converted to an overlay (gifti or otherwise). It is a probabalistic atlas with prior probabilities for each label as well as curvature mean and stddev for each label at each point in space. If you know some C++, you can look at GCSAread() in gcsa.cpp to see what gets read in.

Dear all,
I'm trying to understand the GCS file format as I failed to try an easy conversion with mris_convert.
If mris_convert cannot convert GCS to GIFTI, is there any open description of how the format is implemented?
Thanks very much
Best, Oscar
