Re: [gmx-users] GLUH problem

Dear Jason, I am trying to use pdb2gmx to generate files for my molecules. I have protonated GLU in it. So I am using GLUH as the residue name. However the program complains that Fatal error: Atom HE2 in residue GLU 4 not found in rtp entry with 10 atoms while sorting atoms.

 Dear GMX users, I am simulating the hydrophobic interaction between two 42-aminoacid oligopeptides in pbc conditions with acqueous explicit solvent with all-bonds constraints (LINCS).  In order to allow them to interact -for the first time- I am using pull code.   My pull.ppa is as follows

Thanks TsjerkYes, there was a non-standard amino acid residue and it was not recognising it as part of the protein. I changed the total number of residues in the aminoacid.dat file (which I had not!) and then everything worked ok.AshutoshOn Mar 16, 2006, at 3:09 AM, Tsjerk Wassenaar wrote:Hi Ashuto

You simply can't do that, right now. OPLS isn't implemented into PRODRG, yet (correct me, if I'm wrong). Therefore the atom-naming, etc. maybe wrong. Anyway...a more detailed documentation of the error would be very helpful. regards Maik Goette, Dipl. Biol. Max Planck Institute for Biophysical

Hi Ashutosh, If no index file is explicitly given to grompp, it will use default index group (as if you did echo q | make_ndx -f test_b4pr.gro -o index.ndx) Grompp does not know of definitions given in the .top file with regards to the groups. Does your protein contain some non-standard residues?
