Dear Gurus,

Not sure why this is happening. I tried it a few times.

Using Amber12, AmbverTools12, tleap, MacOSX

here is a summary:

loaded external parameters frcmod, off, (phosphothreonine and
phosphoserine)
loaded pdb
saved pdb
saved prmtop inpcrd
loaded TIP4Pew parameters
solvated in a TIP4PewBOX 12.0
addionsrand Na+ 0

then leap just crashes

 (using default radius 1.500000 for EPW)
  Total vdw box size: 110.230 154.077 120.389 angstroms.
  Volume: 2044656.144 A^3
  Total mass 1073041.258 amu, Density 0.871 g/cc
  Added 51554 residues.
> addionsrand com Na+ 0
15 Na+ ions required to neutralize.
Adding 15 counter ions to "com". 51539 solvent molecules will remain.

any thoughts?

Thanks,
