[Chimera-users] Superimposing and joining

There are several ways to superimpose structures, discussed here:
For example, if you want Chimera to use the sequences of the structures to figure out which atoms to match, you could use the MatchMaker tool under Tools...Structure Comparison (or command "matchmaker"), or if you want to specify exactly which atoms to pair yourself, you could use the command "match" -- there are links to these in the page mentioned above.
The structures are you are matching should be in separate models (opened from separate input files). However, after the superpositioning is done, you can combine separate models into one using the "copy/combine" function in the Model Panel (Model Panel is under Tools... Favorites in the menu) or the command "combine".
I hope this helps,
