Subject:	Geometry Optimisations with Scripts in HyperChem

 Hi,

 I am a HyperChem user. When I wish to run molecular mechanics geometry
optimisations (using MM+) with scripts I find that the termination
conditions (the RMS gradient and the max number of cycles) and the screen
refresh period do not change when the script is run. Instead, I need to
carry out a 'manual' geometry optimization on some molecule (not
necesarily one of those molecules referred to in the script) with the
required settings, stop the optimisation after a few seconds and then run
the script. This is very tedious and I would be very grateful if anyone
could provide a solution.

 If it helps, the offending script commands are typically:

optim-max-cycles 4000
optim-convergence 0.01
optim-algorithm newtonraphson (THIS LINE DOES NOT CAUSE ME A PROBLEM)
screen-refresh-period 200

 Regards,
 Paddy.
