4921	color byattr: min() arg is an empty sequence	guillaume.gaullier@…	Eric Pettersen	"{{{
The following bug report has been submitted:
Platform:        macOS-10.15.7-x86_64-i386-64bit
ChimeraX Version: 1.2.5 (2021-05-24 04:13:57 UTC)
Description
I opened output files (attached) from a ConSurf job in a fresh ChimeraX session. The first sequence in the alignment got automatically associated to the structure. I then ran the command:

color byattr seq_conservation

And got the error message that prompted this bug report.
