[gmx-users] EM of a single molecule

[Tanos]

    Hi folks,
    I wish to perform a EM of my cofactor alone (separated from the 
protein's active site). I have already parametrized the cofactor in the 
Dundee site and have got my .gro and .itp files but I am not been able 
to run the energy minimization in GROMACS with this files. Can someone 
help me. All I want is to perform a EM of a single molecule (different 
of a protein) in a water box.
    Thanks a lot in advance.
