Dear Surfer, I was trying to project a DTI FA image onto the T1 WM surface (for now), and eventually into the fsaverage as in a recent paper: Phillips OR, Nuechterlein KH, Asarnow RF, Clark KA, Cabeen R, Yang Y, et al. Mapping corticocortical structural integrity in schizophrenia and effects of genetic liability. Biological psychiatry. 2011;70(7):680-9.
1. align the lowb.nii.gz from DTI data to T1.mgz image using bbregister to create the register.dat file. bbregister --s 20808 --mov lowb.nii.gz --reg lowb2orig.dat --dti --init-fsl 2. project FA into surface space mri_vol2surf --mov dtifit_FA.nii.gz --reg lowb2orig.dat --hemi rh --o rh.fa.vol2surf2.w --projfrac 0 --interp nearest --surf white --out_type paint Here is the error message when I tried to check the surface in subject T1 space [Minjie-Wus-Mac-Pro:subjects/20808/dmri] minjiewu% tksurfer 20808 rh fa.vol2surf2.w subject is 20808 hemi is rh surface is fa.vol2surf2.w surfer: current subjects dir: /Volumes/Lion/projects/surface/subjects surfer: not in "scripts" dir ==> using cwd for session root surfer: session root data dir ($session) set to: surfer: /Volumes/Lion/projects/surface/subjects/20808/dmri checking for nofix files in 'fa.vol2surf2.w' Reading image info (/Volumes/Lion/projects/surface/subjects/20808) Reading /Volumes/Lion/projects/surface/subjects/20808/mri/orig.mgz surfer: Reading header info from /Volumes/Lion/projects/surface/subjects/20808/mri/orig.mgz nquads=14348288, nvertices=1 ERROR: MRISread: file '/Volumes/Lion/projects/surface/subjects/20808/surf/rh.fa.vol2surf2.w' has many more faces than vertices! Probably trying to use a scalar data file as a surfa Thank you very much for your help.
