I'm a little confused by what PDB assemblies you are talking about that are distributed as multi-state structures, but assuming they are similar to NMR models... you can use intra_fit ( http://www.pymolwiki.org/index.php/Intra_fit )
For example, with 2kgx, we start out with chain a in state 1 and 2 and having an rms of 0.927 and chain b having an rms of 1.143 intra_fit 2kgx and chain a now, chain a has an rms of 0.923 and chain b has an rms of 1.155 intra_fit 2kgx and chain b now, chain a has an rms of 0.952 and chain b has an rms of 1.130 Note, it can take a target state, that all other states are aligned to, etc. On Wed, Nov 5, 2014 at 5:23 AM, Spencer Bliven <sbli...@ucsd.edu> wrote: > Hey, I've been doing a lot of work with PDB assemblies, which are > distributed as multi-state structures.
