This appears to be a bug in ChimeraX's “toolshed” startup code for some machines when ChimeraX is started for the first time. I am going to open a ticket in our bug-tracking system for this, with you on the recipient list. You may be able to circumvent the bug by starting ChimeraX with the “—noexit” flag (that’s two dashes, not one long dash), i.e. chimera-daily —noexit

Hello and good morning,
I have always had a great experience using Chimera and so I was hoping to try out ChimeraX for some of our larger cryo-em data sets. However, following download and an install that did not seem to produce an error message, I can not seem to initialize the program. I have copied the output from the command prompt below. Beyond that, I should probably also mention that we are running the centos-release-7-6.1810.2.el7.centos.x86_64 operating system with intel chips and nvidia graphics cards.
