average_affine(1) The Computational Morphometry Toolkit average_affine(1)


average_affine - Average affine transformations


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.
