ChimeraX (bsky: chimerax.ucsf.edu)

The ChimeraX 1.10 release candidate and daily builds can predict small complexes of proteins, nucleic acids and small molecules using Boltz on your Mac, Windows or Linux computer. rbvi.ucsf.edu/chimerax/data/…

Hey ChimeraX users! ChimeraX-CliX now supports color preview, quick menubar/toolbar search, and many other powerful features to support you. If you are interested in, please download the latest version -> cxtoolshed.rbvi.ucsf.edu/apps/chimeraxc…

ChimeraX AlphaFold prediction is working again. It was broken the past couple days because Google Colab updated the Python library numpy from version 1 to 2. Thanks to ColabFold developer Milot Mirdita for making Colabfold work with numpy 2.

We've moved. To see the latest ChimeraX features such as anisotropic ellipsoids, Foldseek searches, and deep mutational scan visualization check out UCSFChimeraX at BlueSky.

We now have an account on the competing microblogging platform that cannot be named.
