External Email - Use Caution Hello Freesurfer Experts, I'm trying to create a ROI based on the peak from a paper. The peak on MNI305 is X=22; Y=-71; Z=22
to use the mri_volsynth I transformed the CRS from MNI to rh.thickness with the formula: Vrh.thickness*inv(Trh.thickness)*R*T305*inv(V305) (as exemple 8 in https://surfer.nmr.mgh.harvard.edu/fswiki/CoordinateSystems) To obtain R I used: fslregister –s fsaverage –mov $SUBJECT_DIR/fsaverage/surf/rh.thickness –reg rh_thickness.dat So I created my spherical ROI with: mri_volsynth --template $SUBJECTS_DIR/fsaverage/surf/rh.thickness --pdf sphere --dim 1 1 1 1 --dim 1 1 1 1 --c_ras 54690 -13581 175 --o ROI.mgz However, when I try to use mris_fwhm --subject fsaverage --hemi rh --i ROI.mgz --o sphere.sm10.mgh I receive an error ERROR: MRISar1: Surf/Src dimension mismatch. Can someone help me with this?
