Hi,

I am facing a problem with Matching!

Is there any possibility to match two structures, without losing the coordinates of e.g. a dimer unit.

In this case, I want to match a homo-dimer to another similar structure. When I match all of the above mentioned dimers (chains), Chimera will match it all at the same place, so I will have two identical positions. In this case I am losing the steric information about the assembly of the homo-dimer. 

Is there any method, to treat the dimer as one molecule, which cannot be splitted and can be matched on another structure without losing the biological assembly?

It is hard to explain, I hope you get me.

Thanks in advance

Sebastian
