Register for PDB Workshops at IUCr2026

01/11 

wwPDB will be part of the Twenty-Seventh Congress and General Assembly of the International Union of Crystallography (IUCr2026) that will be held August 11-18, 2026 in Calgary, Alberta (Canada).

Register now to join the wwPDB for free, half-day and hands-on workshops that will be held just before the Congress begins.

Enhancing PDB Deposition and Validation Practices (afternoon session on Monday, August 10, 2026)

Pre-meeting workshop: OneDep

This workshop will provide participants with essential knowledge and skills to easily prepare PDB depositions, evaluate structure quality, and utilize OneDep features to streamline and optimize deposition processes.

Through short lectures and hands-on practical sessions, participants will gain proficiency in making successful PDB depositions using available tools for preparation of necessary data and metadata files consistent with OneDep requirements of the wwPDB OneDep system for complete deposition, rigorous validation, and expert biocuration. Participants will develop a comprehensive understanding of information presented within wwPDB validation reports and the importance in assessing data quality. Practical insights will be shared, enabling participants to confidently undertake and complete successful PDB submissions.

Workshop attendees will also become proficient in leveraging various features and tools integrated into the structure determination software packages and OneDep software system, including automatic initiation of new depositions using application programming interface (API) or using traditional web interface via ORCiD to create deposition sessions, and validating deposited data.

Enabling PDB Deposition of Integrative/Hybrid Methods Structures Determined using 3D Electron Microscopy plus Chemical Crosslinking and Other Complementary Approaches with the PDB-IHM System (afternoon session on Tuesday, August 11, 2026)

Pre-meeting workshop: IHM Deposition

This workshop will enable structural biologists to learn about the advantages of using the PDB-IHM system to make complete depositions of 3DEM/Xlinking-MS-based IHM structures and other types of integrative structures to the PDB.

Structures of complex macromolecular assemblies are increasingly determined using integrative or hybrid methods (IHM), wherein complementary experimental and computational techniques are employed. In addition to traditional structure determination methods such as macromolecular crystallography, NMR spectroscopy, and three-dimensional electron microscopy (3DEM), complementary techniques (e.g., chemical crosslinking-mass spectrometry (Xlinking-MS), small-angle scattering, Förster resonance energy transfer, and chemical shift perturbation without NOE restraints) frequently contribute to integrative structure determination.

PDB-IHM, part of the PDB Core Archive, enables deposition, validation, biocuration, preservation, and dissemination of IHM structures. PDB-IHM infrastructure is supported by the IHMCIF data standard (an extension of the PDBx/mmCIF data standard underpinning the PDB) and software tools that ensure FAIR (findable, accessible, interoperable, and reusable) availability of integrative structural biology data. Importantly, integrative structures processed through PDB-IHM receive PDB accession codes and are archived alongside “traditional” single-method experimental structures in the PDB.

The primary goal of this workshop is to facilitate deposition of IHM structures using PDB-IHM functionality, thereby eliminating barriers to fully archiving these structures in the PDB and preventing data loss. Given the predominance of combined 3DEM/Xlinking-MS-based integrative structures, the workshop will highlight these use cases. Through a combination of short lectures and hands-on practical sessions, participants will learn about (a) IHM data deposition requirements, standards, and practices, (b) pre-deposition file preparation, (c) deposition process and workflows, (d) depositing structures through the web interface, (e) submitting multiple structures using an API, and (f) interpreting the information presented in wwPDB validation reports.
