Bacterial glycans are a nightmare to model.

Unusual sugars, missing parameters…

I’ve been working on extending the GLYCAM builder to include them — together with @robertamarchetti.bsky.social, @olivercgrant.bsky.social and the group of Prof. Woods.

Added a little script to chimerax-trimmings to automate the creation of panels for model-map fit figures.

It zones the map around (by default) 40aa parts of each chain (but doesn't cut in the middle of helices). Saves each as a png, metadata to csv.

Saves each view as a scene for tweaking views.

Hey, as a librarian I need to tell you:

Our funding depends on usage.

So go ahead and check out that book even if you don't think you'll finish it. No one will know. Check out that DVD even though you might not like it. Get ambitious in your quest for knowledge.
