Hi freesurfers,
I have an overlay with 4k vertices and I want to decimate it to 1k. This overlay is actually an atlas with a label value for each vertex. My surfaces will have 1k vertices and I need the overlay to 1k so I know which areas each vertex belong to.
I tried to decimate the atlas.mgh but it gives me this error:
ERROR: MRISread: file '/Users/dsinc35/Desktop/projects/parcellation/MMP_atlas_L.mgh' has 0 vertices! Probably trying to use a scalar data file as a surface!
Maybe there is a way to project it?
Any thoughts?
Thanks,
Dorothy
