Use PDB Data to Their Full Extent: Understanding PDBx/mmCIF
Wednesday, May 3, 2023 (1-3pm EDT)

Understand the basics of PDBx/mmCIF data dictionary and file format that underpin archiving of more than 200,000 experimentally determined three-dimensional biostructures in the PDB. Learn about software tools for generating and working with PDBx/mmCIF files, and programmatic access for harvesting PDB data.

Who Should Attend:

  • Professionals and graduate students interested in learning about strategies to take full advantage of PDB data in the fields of:

    • Structural biology
    • Cheminformatics and computational chemistry
    • Bioinformatics and computational biology

Visit IQB for details and registration.

The two organizations will work together in support of the Open Science Data Federation and the RCSB PDB to ensure fast and easy access for researchers in Asia and Oceania. Visit for details.
