Re: [Freesurfer] Conversion fMRI volumes to surface

Yes, use mri_vol2surf. Make sure to use --projfrac 0.5 to sample in the middle of cortex. Run it with --help to get examples.

External Email - Use Caution Dear experts, I’ve done the fMRI preprocessing and now I would like to convert each file (that contains 250 volumes) to surface. Is it correct to use the function mri_vol2surf? Should I use any specific flag because they are 4D files? What is the best way to transform the volumes to surface? Thank you in advance.

Best regards, Marina.
