SBGrid Newsletter: January 2026

Dear Consortium Members and Affiliates,

 

For our inaugural 2026 newsletter, we are sharing a profile on SBGrid member Jean-Philippe Julien, news about upcoming and recent software webinars, a software push that includes 15 updates and 10 new titles, a welcome to nine new members, a reminder that users can request personal installation manager credentials, and one member publication highlight.

 

Our January member tale features Jean-Philippe Julien from The Hospital for Sick Children in Toronto, who interrogates antibodies in the science of global heath, following their stories to guide interventions against infectious diseases like malaria. Julien credits the ethos of his undergraduate college for nurturing his early humanitarian interests and fostering a culture of peace through understanding, the kind of mission-driven international collaboration that he now cultivates in his laboratory.

Calc_level_chimerax 1.0.0 is a new ChimeraX plugin to predict and visualize isosurface levels for 3D density maps. This tool is based on a 3D-CNN initially developed to predict the isosurface levels of 3D density maps, as required by SIREn.

https://github.com/mariacarreira/calc_level_ChimeraX/releases/tag/v1.0.0 

 

ConSurf 1.0.0 is a bioinformatics tool designed for estimating the evolutionary conservation of amino and nucleic acid positions in protein, DNA, and RNA molecules. It leverages phylogenetic relationships among homologous sequences to assess conservation, providing insights into structural and functional importance. ConSurf employs advanced computational methods, including empirical Bayesian and maximum likelihood approaches, to deliver accurate evolutionary rate estimations.

Foundry 0.1.7 is a unified framework for protein design that provides tooling and infrastructure for using and training models including RFdiffusion3 (all-atom generative design), RosettaFold3 (structure prediction), and ProteinMPNN/LigandMPNN (inverse folding). All models rely on AtomWorks, a unified framework for manipulating and processing biomolecular structures for both training and inference. This package enables end-to-end protein design workflows from structure generation through sequence design and validation.

https://github.com/RosettaCommons/foundry

 

ImmuneBuilder 0df4e2a is a deep-learning framework developed by the Oxford Protein Informatics Group for predicting the 3D structures of immune proteins, including antibodies (ABodyBuilder2), nanobodies (NanoBodyBuilder2), and T-cell receptors (TCRBuilder2).
