[gmx-users] error while running pdb2gmx
Hello GROMACS users, I have phosphorylated Serine residue in my protein (140 residues) of interest, now when I run pdb2gmx I get this following error Atom OXT in residue ALA 140 was not found in rtp entry ALA with 6 atoms while sorting atoms. I checked aminoacid.rtp, there is no separate entry for OXT there.When I did the simulation for the same protein prior phosphorylation I did not get this error. What is the reason for this and how should I rectify this error? Please help me with this regard Regards, Hasthi -- gmx-users mailing listgmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/Search before posting! * Please don't post (un)subscribe requests to the list.

Have you followed every one of the steps shown at http://www.gromacs.org/Documentation/How-tos/Adding_a_Residue_to_a_Force_Field#Adding_a_new_residue? If you need further help, we will need more information, which will include (at minimum): 1. Snippet of the PDB file containing the problematic residue 2. Your exact pdb2gmx command 3.

Re: [gmx-users] error while running pdb2gmx
Probably the default behaviour of pdb2gmx for termini is not appropriate for your input. Use pdb2gmx -ter and choose wisely Mark On Nov 13, 2013 12:03 PM, hasthi durgs7kr...@gmail.com wrote: Hello GROMACS users, I have phosphorylated Serine residue in my protein (140 residues) of interest, now when I run pdb2gmx I get this following error Atom OXT in residue ALA 140 was not found in rtp entry ALA with 6 atoms while sorting atoms.
