SBGrid Newsletter: October 2026

Dear Consortium Members and Affiliates,

 

Our October SBGrid news includes an update on the SBGrid CryoEM Tournament scheduled to wrap up in early November, a recording of our recent webinar on cryoCAT, a date for our next webinar on hax-em in Scipion, a software push with 13 updates and three new titles, two new members to welcome, PHP patching notes, upcoming events from our partners at Instruct-ERIC, two science tales from our student contributors that highlight recent member publications, and appreciation for those who remembered to cite SBGrid in their publications.  

 

The SBGrid CryoEM Cloud Tournament is ongoing, bringing together 29 international teams to process the same confidential cryo-EM dataset in dedicated SBCloud environments. Registration is now closed, but the tournament will continue until November 6, with teams competing to produce a scientifically supported reconstruction at the lowest possible computational cost in fully open-source and combined/non-open-source software categories. Supported by AWS, the tournament will provide a community benchmark of cryo-EM workflow quality, reproducibility, and cost efficiency. We will announce the winner in each category in late November.

 

Beata Turoňová, Project Group Leader at Max Planck Institute of Biophysics, kicked off our software webinar series in October with an introduction to cryoCAT, Contextual Analysis Tools for cryo-ET. If you missed her presentation, the recording is now available on the SBGrid YouTube channel.

 

Next up: From static maps to continuous motions: conformational variability analysis with hax-em in Scipion. Join us November 10 to hear from David Herreros, postdoctoral researcher from the Biocomputing Unit, Centro Nacional de Biotecnología.

Software Changes

New Software

The following new titles were added to the SBGrid collection in October:

CryoCodex is a tool for cryo-EM density maps, estimating local map quality, and predicting molecular masks. It produces an enhanced map, local quality scores for both the original and enhanced maps, and a molecular mask to support map interpretation and structural analysis. It also offers a faster cropped-map processing mode and full-map processing. Available in SBGrid at version 1.0.0.

https://github.com/YangLab-SDU/CryoCodex

 

EPU_group_AFIS_ratolonfork takes the XML metadata from an EPU session that used AFIS (Aberration Free Image Shift) for faster acquisition and organizes the collected micrograph movies into RELION Optics Groups. In RELION version 3.1, where these groups were introduced, they can be used to further reduce the effects of high-order aberrations on the data induced by using large amounts of beam-image shift. The output movies.star uses the RELION 5.0 STAR format (# version 50001), matching what relion_import writes. Version 0.2.1 is available in SBGrid.

https://github.com/ratolon/EPU_group_AFIS (code fork from https://github.com/DustinMorado/EPU_group_AFIS)  

 

ESM is a protein modellng package providing ESMC, a protein language model trained on billions of sequences, and ESMFold2, which predicts all-atom protein structures from amino acid sequences with optional multiple sequence alignments. The models support protein sequence analysis, structure prediction, protein-complex modeling, and protein binder design, with pretrained weights available for local use. The version available in SBGrid is 3.4.1.post1.
