I tried to protonate my pdb file using openbabel babel -ipdb fzd8min_renum_SS.pdb -opdb Protein.pdb -h
Then I ran pdb2gmx with the following pdb2gmx -ff amber99sb -f ProteinAmber.pdb -o Protein2.pdb -p Protein.top -water spce -ignh But apparently I am missing a H from my first residue. Is there an easy way to add missing atoms? WARNING: atom H is missing in residue GLU 1 in the pdb file You might need to add atom H to the hydrogen database of residue GLU in the file ff???.hdb (see the manual) ------------------------------------------------------- Program pdb2gmx, VERSION 4.0.5 Source code file: pdb2top.c, line: 704 Fatal error: There were 1 missing atoms in molecule Protein, if you want to use this incomplete topology anyhow, use the option -missing ------------------------------------------------------- -- Jack http://drugdiscoveryathome.com http://hydrogenathome.org -- gmx-users mailing list gmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users Please search the archive at http://www.gromacs.org/search before posting!
