[gmx-users] apbs : pqr file generation problem

I ran a MD simulation, and i wanted to study the resulting structure's
electrostatic potential map. so to do this, parsed out the last frame
as pdb with trjconv and then used PyMol's APBS plug-in with option to
let PyMol generate Hydrogen and Terminies. There's a PQR file
generated but APBS complained that there's 89 atoms missing charges
and calculation wasn't able to ran. I went to PDB2PQR server and
converted the pdb file to pqr file there.
When i loaded it in APBS, nothing happened and eventually it told me
to load another PQR file.
am i missing something here? i'm guessing PDB2PQR doesn't generate a
good pqr file in this case. Maybe it's because it's designed for
processing AMBER file not gromacs?
thanks in advance
