Hi Linda
it should be easy enough to make a scalar map and save it from matlab
using save_mgh or MRIwrite.m. If it's first dimension has nvertices then
tksurfer will know it's a surface overlay and not a volume.
cheers,
Bruce

Hi freesurfers,
Is it possible to make an overlay to load into tksurfer containing any
type of data (for instance, centrality measures computed with graph
theory) for a particular annotation? In the mailing archive, I've found
tips about creating a custom LUT table and making it a segmentation, but
you need the coordinates of the labels for that. In my case, I've made my
own parcellation by using mris_divide_parcellation, so then I would have
to know where to find the coordinates (I don't).
And do you think this is the most efficient method?
Thanks!
