Thank you!
Actually when I run mri_volsynth --help
I can't find --revol. is it the same flag --res?
also what is the relationship between --dim and --volres?

No, you will need to decide how big you want your voxels to be. If you use --volres 1 1 1 1 then that should work. It will put the center of the volume at that coordiate. If you want a single voxel, then use --dim 1 1 1 1 and --volres 6.25 6.25 7.5 1

If the flag --dim (nc nr ns nf) is reffering to the volume dimentions. What is the fourth number (nf ) is standing for ?How big the voxel is in mm2. what is the meaning of voxel resolution ( the flag --res (dc dr ds df) ) and what is the meaning of the numbers dc dr ds df ?The "center" of the volume in mm, where "center" is defined as (Nvoxels-1)/2 where Nvoxels is the number rows, cols, or slices.3. Is the flag c_ras ( c_r c_a c_s) reffering to the volume position. If yes is it in mm or in voxels?Thanks in advance ,John_______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
