We have figured out that our problem is with the ligands.  We are
trying to do the plain minimization of just the 1 ligand in vacuum or
in water.  When can successfully make the 2 input files for SANDER
with no apparent error.  When we minimized in vacuum we used this .in
file
 &cntrl
 imin   = 1,
 maxcyc = 150,
 ntb    = 0,
 igb    = 0,
 cut    = 12
 /
Here is our error

 The system has extended beyond
    the extent of the virtual box.
 Restarting sander will recalculate
   a new virtual box with 30 Angstroms
   extra on each side, if there is a
   restart file for this configuration.
 SANDER BOMB in subroutine Routine: map_coords (ew_force.f)
 Atom out of bounds. If a restart has been written,
 restarting should resolve the error
If we change the maxcyc to 95, the minimization completes.  When we
output the resulting .pdb file we can see that the  2 Oxygens from the
PO(OH)2 groups have collided into each other.
If we put our ligand in a TIP3PBOX and run this .in file
Test run 1
 &cntrl
    IMIN = 1, NCYC = 250, MAXCYC = 300
 /
Minimization completes.  In the resulting .pdb files we can see that
the Oxygens are starting to collide again.  If we change maxcyc to 500
we get this error in our cygwin screen
