Oops- there were some missing cis-peptide parameters for EEFx. Please
copy this file:

   https://nmr.cit.nih.gov/out/protein_eefx2.par

to the toppar/eefx directory of your Xplor-NIH distribution. Do let me
know if you have any problems. In particular, please look for the
presence of the string "ERR" in the output file.

best regards--
Charles
