[Freesurfer] Tracula: Transform streamlines to T1 RAS coordinates

External Email - Use Caution I extract the streamlines for each tract from path.pd.trk to an ascii file and then wish to transform the coordinates to RAS T1 coordinates in millimeters. My results are not correct. Here is the extraction command I'm using. Is this correct? Perhaps
