[Chimera-users] modelling a dimer

[Elaine Meng]

Hi David,
Sorry, multi-chain comparative modelling cannot be done via the Chimera-Modeller interface:
<http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/multalignviewer/modeller.html#comparative>

You would have to use Modeller directly to access functions such as multi-chain modeling that are not available via the Chimera graphical interface..

One could model a monomer and then open two copies of the model and superimpose them onto the monomers of a template dimer (or apply a known symmetry), but that would not necessarily exclude bad interactions between the copies.
Best,
Elaine
