molecular modeling - distance restraints nmr

Hi,
I have question.
i work with oligomers, i did noesy and roesy experiments for that and try to visualize the structure from the distance constraints obtained.

can anyone tell me how to do these in discovery studio.

so i have pdb file, text file having name of the atoms and distance obtained from NMR experiments.

bascially i want to optimize the structure with with distance i obtained from NMR contraints.

looking forward for help
Thanks in advance,
bye
