[gmx-users] Topology files for OPLSAA and RESP charges

[Tanos C. C. Franca]

    Dear GROMACS users,
    I'm trying to start running jobs using RESP charges and OPLSAA force 
field but I am facing problems to generate the RESP charges and the 
topology files for the OPLSAA force field. Does someone knows a software 
to calculate the RESP charges for the ligands and/or, also, to generate 
the .itp files for OPLSAA ?
    With the best regards,
    Tanos C. C. Franca.
