Give it another week or two (or possibly three) :). I’ve been waiting for ChimeraX 1.3 to go into pre-release code freeze prior to building and testing a matching ISOLDE release (also I’ve been absolutely buried under other responsibilities until recently). I’m afraid the current ISOLDE won’t work with ChimeraX 1.3 for multiple reasons, mostly to do with changes in libraries it depends on. — Tristan On 2 Oct 2021, at 14:13, Sindelar, Charles <charles.sindelar@yale.edu<mailto:charles.sindelar@yale.edu>> wrote: Hi all, any chance I can persuade ChimeraX v1.3 (i.e. nightly downloads) to use the current version of Isolde? I would love to use some of the newest features of ChimX together with Isolde, but the toolshed does not allow this (says only ChimX 1.2 is allowed). Are they really incompatible? Can I perhaps “trick” the toolshed somehow? Thanks for all your work to make these fabulous tools. By the way, Tom, Eric, Elaine and team, I *love* the new tool-switching shortcuts, i.e. shift-esc and control-tab. They make my life so much easier and this is a primary motivation for my request (but other new features in 1.3 also). Cheers! Chuck --------------------- Charles V.
