I don't know if we are talking about the same thing. In precedent mail you told me solution #1 was better :
*# Project and smooth onto anatomical surface* (--surf mid : mean surface between pial and white) *mri_vol2surf --mov **cbf.nii.gz --hemi lh --surf mid --o lh.fwhm3.cbf.w --regheader * *subj_id --out_type paint --surf-fwhm 3mris_w_to_curv **subj_id lh **lh.fwhm3.cbf.w * *lh.fwhm3.cbf# Resample cbf to fsaverage mri_surf2surf --srcsubject **subj_id --srchemi lh --srcsurfreg sphere.reg --trgsubject fsaverage --trghemi lh --trgsurfreg sphere.reg --sval * *lh.fwhm3.cbf --sfmt curv --noreshape --no-cortex --tval lh.fwhm3.fsaverage.cbf.mgh --tfmt curv* But you told me : *BTW, why are you changing format from w to curv? Why use curv at all? I'd use mgz or nifti.* At this point I don't know what this means ?
