Hi,

VMD 1.8.3 will work only with Numeric Python version 22. Try

Thanks,
Justin

The spirit of Plato dies hard.  We have been unable to escape the
philosophical tradition that what we can see and measure in the world
is merely the superficial and imperfect representation of an
underlying reality.
