<DIV><FONT face=Arial size=2>Hi all<BR>My system contains receptor protein with
ligand (inside the active site of the receptor).<BR>I need to constrain distance
between OH group of one of the tyrosines (of the receptor) <BR>with OH
group of the ligand. Is there a way to constrain distance between
two atoms <BR>of two different molecules in GROMACS3.3. ? <BR> Please give
me some suggestions, thank you in advance.<BR>Michal.
