Hi Dr. Case,
Thanks for the response. I misread the Amber 9 manual (page 196;
6.12.9; Direct dipolar coupling restraints: makeDIP_RST) and thought
that only N-H and Ca-H RDCs were supported, whereas the limitation is
on makeDIP_RST. I will try to make the modifications to the
makeDIP_RST script to create input files for my other RDC data.
Thanks,
Doug
