[Xplor-nih] Python interface: AnnealIVM vs initDynamics

[Ryan MB Hoffman]

Hi all:

I'm trying to understand why I would use one or the other. The two are 
often both used in example scripts.

For example:

from ivm import IVM
test1 = IVM();
test2 = test1;

from protocol import initDynamics
run1 = initDynamics( test1, [ARGS1] )

from simulationTools import AnnealIVM
run2 = initiDyanmics( [ARGS2], ivm = test2, [ARGS3] )

run1.run()
run2.run()

How are run1 and run2 different, and how do I use either appropriately?

Thanks,

Ryan
