You should register the fMRI to the anatomical with bbregister. Run it with --help for more info, also see the wiki tutorial on fMRI integration. You can then sample the time series to the surface with mri_vol2surf doug On 4/1/12 1:52 PM, Kaveh Kohan wrote: Hi FreeSurfer Users, I am new to

Hi Gabor - If you provide the DWI dicoms directly, tracula uses mri_convert to convert them to nifti, and mri_convert doesn't read directions from the header, it looks them up from: $FREESURFER_HOME/diffusion/mgh-dti-seqpack/ This should be fine assuming you use the same standard
