Hi,
I'm trying to run a simple simulation of a DNA hairpin pdb entry 1pqt.
When I run pdb2gmx with the G43a1 force field I get the error:
Warning: 'DG' not found in residue topology database, trying to use 'DGUA'
-------------------------------------------------------
Program pdb2gmx, VERSION 4.0.5
Source code file: pdb2gmx.c, line: 429
Fatal error:
Atom O5' in residue DGUA 1 not found in rtp entry with 25 atoms
while sorting atoms
-------------------------------------------------------
any hints?
Atom naming in the coordinate file must match what is expected in the .rtp file.
Check out the .rtp file and adjust the coordinate file as necessary. With
nucleic acids, it's usually a difference between ' and * in the sugar.

Thanks,
