This script allows files in selected CHARMm and CNX (CNS/XPLOR) constraint formats, as well as a "free format" constraint format, to be loaded from a file and read into Discovery Studio. DS Constraint objects are created and distance or torsion monitors are then displayed on the molecule. An attempt is made to color code the constraints based on whether the constraint is satisfied in the current conformation.
The format details and limitations are given in the header. Example input and output are included in the zip file along with the DS 2.1 perl script.
