[Freesurfer] From SUMA Dset file to Freesurfer file( overlay an gii file on fsaverage brain)

Dear Freesurfer experts, If you are not skilled in SUMA, you can directly skip to part 2. I have a trouble when I converted a SUMA dset file to Freesurfer file which can be overlayed on Freesurfer's fsaveraage brain. Part 1: converting SUAM dset file to Freesurfer gii file I followed the
