use the filtered func data. reg.lta the output of bbregister (might also be a .dat file). If the output is on fsaverage, then you can use nifit as output. FV will read mgh, mgz, nii, nii.gz, as well as dicom

Hi Doug,
I have the data both in its native functional space (e.g. filtered_func_data). I also run bbregister so have the transformation matrix to register it to the T1 (e.g. anat2exf.register.dat). Do you suggest running vol2surf on the filtered_func_data file? Also is reg.lta generated by FreeSurfer during recon-all or do I need to generate this file? I would like to end up with the filtered_func_data file on the fs_average surrface, which would require the file format to be .mgh to load this an overlay on Freeview, right?

If you have the data in the native functional space, then just mri_vol2surf --mov func.nii --hemi rh --reg reg.lta --trgsubject fsaverage --projfrac 0.5 --o rh.func.fsa.mgz

Hi experts,
I have some fMRI data that I have pre-processed in Feat. I want to resample a single subject's data to the fs_average surface but unsure of the most optimal way of doing this. At present I am warping the functional data to the MNI brain in the volume (using FSL's applywarp) and then resampling to fs_average using the following command.
- mri_vol2surf --src filtered_func_MNI.nii --out filtered_func_surf.mgh --hemi rh --mni152reg
My question is whether you think this is the most appropriate approach, and/or if there is way to move directly from native volume to fs_average surface without needing to go via MNI volume?
Best wishes, Mason
