Hi Catherine, (Cc’ing chimera-users@cgl.ucsf.edu which is the recommended address for Chimera questions) As the message suggests, your models #0 and #1 are not rotated from each other. I’m guessing that you opened the same dimer structure twice and then matched it to itself. For example, if your structure contains chains A and B, it sounds like A was matched to A and B to B, so there was no rotation (zero degrees). You have to make sure that the matching is A to B and B to A. To do this with the “mm” command, for example, you would have to specify the chains AND use the “pair ss” option. There is a specific example of commands for structure 5hvp in this previous post. <http://plato.cgl.ucsf.edu/pipermail/chimera-users/2017-April/013290.html> I hope this helps, Elaine ---------- Elaine C.

Hi Eric, I am trying to find Axis of Symmetry in Dimers. I executed mm command, and then tried to execute measure rotation #0 #1 command. It throws me an error:

I am using chimera version 1.11.2. Can you please help me with this? Thanks, Catherine
