Case sensitive chain IDs not working in wildcards

[Tristan Croll]

The following bug report has been submitted:
Platform:        Windows-10-10.0.19041
ChimeraX Version: 1.1 (2020-09-09 22:22:27 UTC)
Description
Working with a large model composing scenes for figures, and every now and again ChimeraX appears to "forget" that the model has case-sensitive chain IDs - commands targeted at, for example, /A* start acting on /a* as well. Haven't pinned down what the trigger is.

[Tom Goddard]

There is a StructureData (C++ base class for Structure) attribute lower_case_chains which determines whether chain ids in commands are interpreted as case insensitive or case sensitive. The idea is that if all chain ids are upper case then the command accept upper or lower case chain ids, but if the the structure has upper and lower case then you have to use the correct case in the command.

Eric is on vacation (all Fridays this month) and can provide more info next week.

[Tristan Croll]

Yep. What's weird here is that at some point during my (very long) list of commands (color, transparency, show/hide, surface, save/restore session, etc.) the commands went from respecting upper/lower case chain IDs to not respecting them. This happened on two occasions today. All manipulations I made were aimed at visualisation, not editing - no addition/removal of atoms or renaming of chains.

Ah - I see the problem now. It's wildcard selection that's broken. In this model, with chains aa-ap and AA-AX, then:

sel /aa ;# selects only chain aa
sel /aa-ap ;# selects chains aa-ap as expected
sel /a* ;# selects all​ chains starting with a or A

I cannot reproduce this behavior.  If I open 5y6p, "sel /k*" and "sel /K*" select disjoint sets of chains, as per these images ('k*' left, 'K*' right):



I guess I need more info to reproduce the behavior you're reporting.
