Hi Lorenzo
we need more information if we are going to be able to help you. What is not working? You should be able to use bbregister on the fMRI data to register it to the surface, then mri_vol2surf to sample it onto the vertex mesh.
Note that you should avoid .img format! Use nifti instead - analyze doesn't have enough information to reliabily distinguish left from right.

Dear Freesurfer users,
I was wondering if it is possible to transform functional connectivity images (.img format) derived e.g. from an ICA of resting state fMRI data into vertex space reflecting cortical thickness (derived from the Freesurfer pipeline on anatomical data). We have been trying hard with commands as mrivol2surface and bbregister without much success. Do you have any suggestions why it is not working? Can a correspondence of activity and structure be implemented in Freesurfer only if the activation maps are derived from the freesurfer pipeline? Any help is welcome! Cheers,
Lorenzo
