Cyclic Peptides in NMRViewJ

[foster.281]

Hello Bruce et al.,

How to specify a cyclic peptide in NMRVIewJ?

We’re trying to use NMRViewJ to assign NOE peaks of a cyclic peptide. We read the topology file from a PDB, but it seems that NMRViewJ does not know the peptide is cyclic, and has added terminal amino hydrogens, and the atom numbers don’t match the atom order in the assignment table.

Not sure if that’s the nature of the problem, however, when we try to peak-match, we get invalid atom ID errors.

Suggestions?
