Hello,
Thanks David for your helpful answer. I still have some problem getting
what I want and I think it is because there are steps which I should do but
I am simply not aware of them. Can anyone please help me with this problem:
-I have two residues and for both of them I have the following files:
pdb,mol2,frcmod
-using packmol, I put these two residues in a certain number of water
molecules in a box and I get a file: mixture.pdb (which needs editing to be
xleap/antechamber ready)
the problem now is how to get prmtop/inpcrd files from mixtures.pdb in
xleap?
in case I load the mol2/frcmod files which I had for separate residues, my
guess (and raw try) tells me that xleap does not relate them to mixture.pdb
file.
should I do something here or should I use antechamber on mixture.pdb to
get the mol2 file and then use it in xleap? Is it ok to use antechamber on
solvated residues?
To sum up, my problem is that I have a pdb but I cannot tell xleap where to
get the mol2/frcmod parametres for it. Please let me know if you need any
extra info.
Best regards,
Azade
