Experimental MMTF load support in PyMOL v1.8.4

We are happy to announce that the release of PyMOL v1.8.4 has an experimental MMTF load support.

End of support for version 0.2 on November 1, 2016.

With the release of MMTF version 1.0 we will end support for version 0.2 on November 1st. Until then the wwPDB archive files are available at and will be updated on a weekly basis for version 1.0 and 0.2. Please update your libraries as soon as possible. The latest versions of our Java, Python and JavaScript libraries support version 1.0. If you need more time updating please don't hesitate to contact us.

MMTF 1.0 released on August 15, 2016!

The MMTF project is pleased to announce the release of MMTF v1.0. MMTF is an open-source binary file format optimized for efficient transmittion and fast parsing of 3D structures of biological macromolecules.

Today MMTF ships with support for working with: The major feature added in this release includes the transformation matrices that describe noncrystallographic symmetry operations needed to create all molecules in the unit cell (see the changelog). In addition to the new changes, this release saw significant advancements in stability and usability:
We released MMTF 0.0.1 over four months ago (April 26, 2016). This extensive testing period enabled us to stress our server under a weekly update routine, find any issues that might impact the stability of converting mmCIF to MMTF, fix them, and confirm they were fixed. This all makes MMTF 1.0 our most stable release to date.
We designed MMTF to make it easy to incorporate to your projects. Our format is already supported by 3Dmol, MolSoft ICM v3.8-5 and Jmol v14.5.4 has a preliminary MMTF reader.

The 1.0 release represents a milestone where we believe MMTF is ready for general use. For more details, see specification of MMTF 1.0.
