Thanks to contributions by Rob Turnbull, the process for converting TEI collations to various phylogenetic software input formats now makes better checks for malformed inputs. Check it out on https://github.com/jjmccollum/teiphy or get it with pip install teiphy30 Aug 2026 00:20 +0000at://did:plc:bjpvbf2rw7addumiauyv2vbf/app.bsky.feed.post/3mub4ntafkc2zhttps://bsky.app/profile/joeymccollum.bsky.social/post/3msw7sk2gj22kSomething fun's going on in the bottom margin of GA 2675 (Holy Monastery Panagia Kato Xenia MS 14, 14th century) on this page of Ephesians, but I'm not quite sure what! I thought it might be a practice alphabet, but it doesn't look like the Greek alphabet to me. Any ideas?12 Aug 2026 22:52 +0000at://did:plc:bjpvbf2rw7addumiauyv2vbf/app.bsky.feed.post/3msw7sk2gj22khttps://bsky.app/profile/joeymccollum.bsky.social/post/3msjkgm2uw22yThe open-cbgm library (https://github.com/jjmccollum/open-cbgm) and open-cbgm-standalone utility (https://github.com/jjmccollum/open-cbgm-standalone) have both been updated to v2.1! In both cases, dependencies and build settings have received a needed update. (Thanks to Daniel Ridings for reporting build issues!)

In the Latin side of GA 628 in Eph 3:1, there is a marginal note/correction and a supralinear correction, both pictured in the screenshot below. My questions about these two features follow in order.09 Jul 2026 14:40 +0000at://did:plc:bjpvbf2rw7addumiauyv2vbf/app.bsky.feed.post/3mq7uhr55ts2ihttps://bsky.app/profile/joeymccollum.bsky.social/post/3mq3b6zjxgc2pExciting work by a great team!

I'm interested in scenarios where branches' mutation rates depend on birth/speciation rates.27 May 2026 02:47 +0000at://did:plc:bjpvbf2rw7addumiauyv2vbf/app.bsky.feed.post/3mmsik6gywk2uhttps://bsky.app/profile/joeymccollum.bsky.social/post/3mm6athn63c2eThe slides for my talk at KU Leuven's upcoming GA 629 conference are coming together nicely! I made a few tweaks to the KU Leuven LaTeX presentation style at https://gitlab.kuleuven.be/campus-geel/templates/latex-ku-leuven-beamer to match some more recent official PowerPoint templates better.

But this might be the first time I've seen a nomen sacrum corrected to this end! Here's Eph 2:2 in GA 1956:12 May 2026 20:55 +0000at://did:plc:bjpvbf2rw7addumiauyv2vbf/app.bsky.feed.post/3mloof4relk23https://bsky.app/profile/joeymccollum.bsky.social/post/3mlbm2ysrks2bteiphy v0.1.26 is out with another requested feature! If your collation contains many correctors and you only want to fill in the extensive ones (presumably so you can drop out the rest as fragmentary), you can do so with the new --fill-correctors-threshold option. https://github.com/jjmccollum/teiphy (1/3)07 May 2026 16:09 +0000at://did:plc:bjpvbf2rw7addumiauyv2vbf/app.bsky.feed.post/3mlbm2ysrks2bhttps://bsky.app/profile/joeymccollum.bsky.social/post/3ml4mpbry6s25A great introductory post on how the CBGM works and why it was developed for NT textual criticism, including a bibliography of helpful resources for further reading!
