I want to use g_lie function of gromacs to calculate the binding free energy
og a ligand with the protein. For the same I need to run two MDS, one for
ligand only and one for ligand+protein complex (please correct if I am
What are the checks that I should take care in this case, e.g. Do I need to
keep the same box size, or same number of solvation molecule in two cases ?
or similar things.
And also I am unable to run the MDS for ligand only as it gives the error
...Residue 'D4N' not found in residue topology database.....
For the ligand+protein complex I followed the drug-enzyme tutorial by J E
Kerrigan, and it worked well.
How can I run the MDS for ligand only ?................................ If I
will take the .itp from the PRODRG and use it as .top and bypass the pdb2gmx
step as mentioned in the tutorial, will it work ? (consider the difference
in two cases one is ligand only and other is ligand+protein ).
