best_rigid
PURPOSE
best_rigid is used to find the rigid transform that best approximates the non-linear map given to it. This can be helpful in finding a simple transformation between two images when the images differ substantially and there are many spurious local perturbations in the pairwise map produced by the register program.
TYPICAL USAGE
best_rigid -input input.map -output output.map
COMMAND LINE OPTIONS
-input input.map
specifies the potentially non-linear map to use as input
-output output.map
specifies the name of the map to write as output
