Allocate fewer processors - one should do.
It does run with two processors but again stopped for a different error this time. I pasted the output file here:
NMR restraints: Bond = 0.996 Angle = 0.000 Torsion = 0.000
===============================================================================
NSTEP = 9000 TIME(PS) = 9.000 TEMP(K) = 324.18 PRESS = 0.0
Etot = 126.7326 EKtot = 75.3720 EPtot = 51.3606
BOND = 22.7783 ANGLE = 45.8167 DIHED = 48.3483

EELEC = -171.6326 EHBOND = 0.0000 RESTRAINT = 0.6639
EAMBER (non-restraint) = 50.6967

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
----------------------------------------------------------------------------------------------------------------------------------
I rerun the same job but using the restart file which was written from the previous run but yet it did not resolve it.
I had no problem running SMD in explicit water using restart files extracted from MD ...but trying to run the same simulation in vacuum seems to be not straightforward at all ...
thanks
