Many thanks for the answers @Timothy I know that probtrackx2 support surfaces but I did not manage to make it work without hectic results (fiber crossing the surfaces used as stop, combinatorial counting of endpoints ... ), even if FSL seems the most able to process multi-shell data. @Donna I alr

As far as I know, caret5's multi-fiducial mapping is volume->surface rahter than surface->volume. The caret_command method works, but you'll need to convert HCP surf.gii -> caret5 coord/topo (caret_command -file-convert -sc …). And your label.gii or func.gii will need to be converted, too (car

Workbench currently doesn't have a way to do that. caret5 has a way to do this (caret_command -surface-to-volume, and there is another method called multi-fiducial mapping, though I'm not sure how to invoke it), though you may need to do some file conversion. On a side note, FSL's probtrackx does

Hi hcp experts, I was wondering if anybody knew a way to map back to volume the values in a surface gifti from HCP data. The main interest is to create ROIs on the surface using this topological constraint and then send it back to volume for let say a tractography software which does not support s
