dmri_image_transform

 Change coordinate system of specified image.

 [Usage]
    dmri_image_transform(from_file, to_file, to_ref_file, ...
                         direction, transinfo_dir);

 [Input]
        from_file : original niftigz file.
          to_file : transformed and newly create niftigz file.
      to_ref_file : reference image file of to_file.
        direction : transform direction   [string]
                    'fs2struct'          : from freesurfer coord to T1 coord.
                    'struct2fa'          : from T1 coord to FA coord.
                    'struct2fa_nointerp' : from T1 coord to FA coord with interp.
    transinfo_dir : The directory which is including transform files.
