Recently, the PDB-Dev team participated in the BioExcel webinar series. The webinar presentation was titled "PDB-Dev: A prototype system for archiving integrative structures". The recorded version of the webinar is available on youtube.

3D visualization of structures using Molstar is now available on PDB-Dev. Structures in PDB-Dev can be directly visualized from the respective entry pages. Molstar can visualize atomic as well as multi-scale structures.

Integrative structures can also be visualized online using the Molstar viewer.

Molstar is an open collaboration started by PDBe and RCSB PDB to provide a technology stack for data delivery and analysis tools of macromolecules.

Molstar is under active development. Please report any issues on the Molstar GitHub site.

The PDB-Dev web interface has been revamped to provide dynamic, responsive and mobile-friendly web pages. The newly designed website has been made possible due to an overhaul of our backend infrastructure.

The PDB-Dev website now includes a new service that facilitates search and retrieval of integrative structures archived in PDB-Dev. Simple search using macromolecular names (e.g., nuclear pore complex), entry identifiers (e.g., PDBDEV_00000012), experimental methods used (e.g., NMR, 3DEM, CX-MS), author names (e.g., Sali), software used (e.g., IMP, HADDOCK, ROSETTA), and several other keywords are now supported. Search results can be downloaded as CSV or EXCEL files.

We have also added individual entry pages that provide a summary of the structure (title, description, authors) along with other details regarding the citation, software, input data, and links to related resources and downloading the structure.

We welcome feedback from our users. Please send any comments or suggestions to

In March 2019, a satellite workshop titled “Working towards federating structural models and data” was held at the Biophysical Society Annual meeting in Baltimore, Maryland to assess current progress and discuss further requirements for archiving integrative structures. The primary goal of the workshop was to bring together experts from different scientific communities contributing to integrative structural biology and build consensus for addressing the challenges involved in creating common data standards, building methods for federated data exchange, and developing mechanisms for validation of integrative structures. A whitepaper summarizing the outcomes of the workshop was recently published in the journal Structure.

The multi-scale integrative structures downloaded from PDB-Dev can be visualized using the ChimeraX software.

ChimeraX is under active development. It is recommended to use the Daily Build of ChimeraX for visualization.

Please refer to the Daily Build Notes for information regarding operating systems currently supported by ChimeraX.

The integrative structures can be downloaded as text files (use right click + save as) and opened on ChimeraX using the "format ihm" command line option along with the complete path to the downloaded file:

open path/to/myfile.cif format ihm

Alternately, the following command can be used to directly visualize an entry from PDB-Dev, eg: PDBDEV_00000010.

open 10 from pdbdev ignoreCache true

Recent Updates

The PDB-Dev entry files have been recently updated to comply with updates in the IHM dictionary.

Older files downloaded from PDB-Dev will not be supported on the latest ChimeraX. Similarly, the new PDB-Dev files will not be supported on older versions of ChimeraX.

Please download a fresh copy of the file from PDB-Dev and/or clear the ChimeraX cached IHM files (delete ~/Downloads/ChimeraX/PDBDev) for visualizing the updated files with the latest ChimeraX.
