Created by: Hayley Reynolds Date: 11/2/05 Note that the bicubic-linear muscles in this directory did not use the right hand rule for the xsi directions when created. - to change the xsi directions to the right hand rule use the given perl script 'change_3dxi.pl'. There are restrictions for the use of this perl script as detailed inside. Also, note that some muscles have separate files for the muscle's muscle and its tendon (either separate backend or frontend files).
