Thank you!

I changed the residue names in the .pdb file to LYQ and GLQ

LYQ NZ 1 GLQ C 1 0.13 LYQ GLQ

pdb2gmx -f ubc7_94_t48_newgmx1.pdb -o processed.gro -water tip3p -chainsep interactive -ignh -rtpres


Program pdb2gmx, VERSION 4.5.4

Source code file: resall.c, line: 581

Fatal error:

Residue 'LYQ' not found in residue topology database

For more information and tips for troubleshooting, please check the GROMACS

I checked http://www.gromacs.org/Documentation/File_Formats/Topology_File

But as you see from the previous mail, I included LYQ and GLQ to the force field. Maybe I missed something?



Apparently you did not add .rtp entries for these residues. See http://www.gromacs.org/Documentation/How-tos/Adding_a_Residue_to_a_Force_Field for all necessary steps and be sure you've completed all of them.
