Dear fsl-experts,
I am trying to project connection probabilities onto a freesurfer cortical surface.
As I understand from the documentation (built 501), surf_proj should be the right tool.
My data:
paths_fnirt: fdt_paths fnirted to freesurfer space (checked, fits on brain.nii.gz from freesurfer recon.)
lh.white.asc: converted brain surface file (checked in freeview)
So I used:
surf_proj --data=paths.nii.gz --surf=lh.white.asc --meshref=brain.nii.gz --out=testproj
(I might not need the --xfm option since my 3D data is already in the same space as the reconstructed brain surface.)
Everything works well and I get an ascii-file. However, I cannot open this file either with freeview, tksurfer or tkmedit.
I could also upload the output file ("testproj")
Somehow I was expecting to get a cortical surface file that could be color-coded for connection probability. But am not sure if my approach is feasible...
I would appreciate any help!
All the best,
Bastian
