I am modeling a ligand using FFTK and I am observing a strange behavior in
the water interaction step.
In FFTK I define hydrogen bond acceptors and donors. and water molecules
are placed in an initial conformation for Gaussian energy calculation.
I run the Gaussian calculations and the results for interactions where my
ligand is a hydrogen bond ACCEPTOR (oxygen atoms from ligand interacting
with hydrogen from water) are ok, with the system finding the minimum
energy distance as a few Angstroms. However, the results in which my ligand
is hydrogen bond DONOR (hydrogen atom from ligand interacting with oxygen
from water), the water molecules go far away, not finding a near energy
Does someone who faces this problem sometimes could help me?
