Hi Daniel,
Sorry for the intensely late response and the vague question.
Here's what I have:
1. surfaces converted from FreeSurfer of the subject's anatomy
2. a NIfTI file with a frequency tuning map (each voxel has a value range 1-8 depending on the frequency it activates most highly to) generated through an SPM analysis
What I would like to do:
1. project the tuning map onto the surface in such a way that I can smooth the map after it is in surface space, rather than smoothing in volume space and then projecting it because the volume space smoothing has caused some spacial accuracy issues once on the surface.
I have previously only been using SUMA in conjunction with the AFNI overlay/underlay, using the anatomical as the underlay and the tuning map as the overlay. I have messed around with 3dVol2Surf, but I don't think I am inputting appropriate data in the grid_parent option.
Any advice is very much appreciated!
