2679	Rotamers wrong for moved structures	j.r.lewandowski@…	Eric Pettersen	"{{{
The following bug report has been submitted:
Platform:        Windows-10-10.0.17763
ChimeraX Version: 0.91 (2019-12-11)
Description
Occasionally, I get a strange behaviour with the Rotamers tool. I think it happens to molecules that I have moved using Translate Selected tool. When I select the different rotamers the side chain is placed in the position for where, I am pretty sure, the original residue was instead of the translated coordinates. As a result I get a rotamer with, e.g. 10 A CA-CB bond and the side chain far away from the molecule (see example on the attached image). I tested by moving the molecule a few times and changing the rotamer. Indeed, where the side chain is relative to the molecule (and CA-CB bond length) depends on how far I am from the original coordinates.
