Hi again,
I use MDL ISIS draw (free) software for drawing my ligands, save it,
and port it through Babel, which would give me, mol2 or pdb output
files, which i can use as input ligand file in DOCK. i hope this is
what was asked for!! (and please tell me, if my method mentioned above
is ok?)

is there anyway, i can know, what scoring function is in use, and can
i change it in DOCK?

With regards,
