[modeller_usage] Modelling Asymmetric Unit with Symmetry

[David Johnson <da.johnson.a AT gmail.com>]

I am trying to model a mutation of a molecule whose .pdb file contains 
the asymmetric unit as well as definitions for its symmetry operations. 
I would like to determine the effects on the biological assembly a given 
mutation may have and would therefore like to include the space group 
symmetry in the model. I have looked through the online manual and have 
thus far been unable to produce such a model.
