Description

The following bug report has been submitted:
Platform:        Linux-4.15.0-147-generic-x86_64-with-glibc2.14
ChimeraX Version: 1.2.5 (2021-05-24 04:13:57 UTC)
Description
I turned on side-by-side stereo ("camera sbs") then turned it off again ("camera mono"), then went into the validat pane and tried to pick a bad rotamer to view.

Summary:	ChimeraX bug report submission → 'SplitStereoCamera' object has no attribute 'field_width'

Reported by Randy Read

Cc:	Tom Goddard added
Owner:	changed from Tom Goddard to Tristan Croll

ISOLDE code navigate.py is trying to use camera.field_width for non-orthographic cameras. That attribute is only available for orthographic cameras.

comment:3 by Tristan Croll, 4 years ago

Resolution:	→ fixed
Status:	assigned → closed

field width is now only used when the camera is orthographic.
