[modeller_usage] parallelization with randomize.dihedrals?

[R K Belew <>]

hi Ben et al,

just when i thought i had my parallel version working nicely...
i tried doing a run that had only one difference from previous:

	a.rand_method = randomize.dihedrals
vs previous:
    	a.rand_method = randomize.xyz

but this throws an error:

any guesses as to why?  thanks again for your help.
