register T2/PD to T1 in Talairach space

pipeline_t2tot1.pl <xfm> <t1> <t2> <out_xfm> <out_t2> [options]

DESCRIPTION

pipeline_t2tot1.pl registers a T2-weighted (or proton-density) volume to a T1-weighted volume in Talairach stereotaxic space. The script uses intra-subject cross-modality registration to align the T2 volume to the T1, producing a transformation file and a resampled T2 volume in Talairach space.

The input T1 Talairach transform is used to bring both volumes into stereotaxic space. Intensity correction can be applied independently to the T1 and T2 volumes using the –correct_t1w and –correct_t2w options. A model directory and name must be specified for the registration reference.

OPTIONS

--verbose
Print progress information during processing.
--clobber
Overwrite output files if they already exist.
--correct_t1w
Apply intensity correction to the T1-weighted volume.
--correct_t2w
Apply intensity correction to the T2-weighted volume.
--model_dir <dir>
Path to the directory containing the reference model files.
--model_name <name>
Base name of the reference model.

EXAMPLES

Register T2 to T1 in Talairach space:

pipeline_t2tot1.pl tal.xfm t1_native.mnc t2_native.mnc \
  t2_to_t1.xfm t2_tal.mnc \
  --model_dir /opt/minc/share/icbm152_model_09c \
  --model_name icbm_avg_152

Register with intensity correction on both modalities:

pipeline_t2tot1.pl tal.xfm t1_native.mnc t2_native.mnc \
  t2_to_t1.xfm t2_tal.mnc --correct_t1w --correct_t2w \
  --model_dir /opt/minc/share/icbm152_model_09c \
  --model_name icbm_avg_152
