cmtk-average_affine (1)

average_affine [options] x0 [x1 ...] WHERE x0 ... xN is [{-i,--inverse}] affine transformation #. (If the first transformation in the sequence is inverted, then '--inverse' must be preceded by '--', i.e., use '-- --inverse xform.path').

This tool computes the average of a sequence of user-provided affine coordinate transformations.
