I want to do dynamics on a cyclic polypeptide. The peptide contains a residue that is not standard Ornithine. I have added [ORN] to the ffoplsaa.rtp file and the aminoacids.dat file.I have put these in the working directory and also in the library. If I grep these files [ORN] is there but i still get an error message below.Is there some database i am meant to edit.
