2270	Bad automatic contouring	tic20@…	Tom Goddard	"{{{
The following bug report has been submitted:
Platform:        Linux-3.10.0-957.12.2.el7.x86_64-x86_64-with-centos-7.6.1810-Core
ChimeraX Version: 0.91 (2019-07-27)
Description
Automatic map contouring seems to be failing on some maps. This is the second one I've opened today where it's defaulted to a slightly negative contour (displaying as a solid cube). Doesn't appear to be anything wrong with the map itself... box is on the large side relative to the size of the positive density region.
