Re: [IMP-dev] more than one molecular hierarchy

[Daniel Russel <>]

There are two solutions:
1) use multiple hierarchies, see the custom_hierarchy example fragment 
(or the HiearchyTraits docs) for how to do this
2) use a TableParticleRefiner. It is pretty straight forward, but was 
just written, so you mileage may vary
