talairach_avi

This is incorporated in Version 4 and later. Front-end for Avi Snyders (WUSTL) image registration tool. Computes the talairach transform that maps the input volume to the MNI average_305.

Note: does not add the xfm to the header of the input file. See mri_add_xform_to_header.

In recon-all -talairach:

creates transforms/talairach.xfm
talairach.xfm is now used for the eTIV computation
verify transform by invoking (from the subjects mri directory):

tkregister2 --targ $FREESURFER_HOME/average/711-2Cs_mni_average_305.4dfp.img --mov ./T1.mgz --xfm ./transforms/talairach.xfm --reg delme.reg
