Hi Doug,<br><br>Thanks! I was wondering: when I have selected
&quot;Calculate Identity Matrix&quot; to overly functional data on the fly in the
tksurfer gui before, it seems to align it perfectly to the freesurfer
anatomical. Is there a way to output the matrix that it's using as a
register.dat file? I was trying last week to make the file using
tkregister2 and for some reason it always came out misaligned (that's
why I started just using the gui). mri_vol2surf is working to make
surface overlays, but they don't line up right, presumably because it's
using the old register.dat file from tkregister2.<br><br>mri_vol2surf --src 003/bold/03.trim_time.tval<div id="mb_2">+orig.BRIK --src_type afni --srcreg register.dat --hemi lh --projfrac .3 --out trim_time.tval.surf.5 --out_type paint
