Python-based Hierarchical ENvironment for Integrated Xtallography

PHENIX nightly build distribution

These installers are built automatically using the current source code and are automatically tested. We do not release installers that have known major problems, so these builds should be suitable for most purposes. Official releases and builds deemed to be "stable" are noted as such and highlighted in bold type.

If you do use the nightly builds, we recommend updating frequently; once a build disappears from the list here, it can be assumed to be obsolete.

If you encounter errors when using any of these builds, please update to the most recent build before sending a bug report. (It is generally a good idea to update frequently anyway, since the code changes rapidly.)

Note: Phenix installers are available for 64-bit Windows systems (Windows 7 or newer). Some programs or features are not available because of limitations of the Windows platform; please read the platform support notes for details. We appreciate any feedback about bugs or inconsistencies.

You will need proper authentication to download the installer; see the main download page for details.

General Note:

  • This release will have a fundamental change in how dependencies are managed. We are moving towards using conda, which will provide better compatibility and consistency across all platforms (linux, macOS, and Windows). Please contact us at bugs@phenix-online.org if you have any issues.
Windows Note:
  • This installer does not come with the Microsoft Visual C++ 2008 Redistributable Package. This is required if you do not already have it installed. You can get a copy from here. Just run the "vcredist_x64.exe" installer. The next release candidate will contain this file.
