Hi again Chimera Team,

I have a large macromolecular structure, and I want to, at random, substitute some of the separate models for a variant form.

Is it possible to do this through chimera, e.g. via python? It seems to me it would basically be a case of:

1. enumerate the list of open models
2. pick a model at random
3. either open a new model, fit it to that model, then close the old one, or somehow get the old models co-ords, close it, then open the new one in its place from a specified file path

Any alternative suggestions if there's a better way to do this would be great as well.

Thanks
