Plugins are external modules that add functionality to PyMOL.
Plugins can be single Python files (*.py) or directories with an
__init__.py file (see PluginArchitecture).
Looking for available Plugins? Browse the plugins category.
To install a plugin, open PyMOL and then go to
- Plugin > Plugin Manager > Install new plugin
You will have the option to install from a file on your computer (*.py, *.zip) or directly from the PyMOLWiki by providing the wiki page url.
See the Plugins Tutorial.
Before Version 2.0
Plugins written with PyQt5 do not run in PyMOL 1.x.
PyMOL 2.x has a legacy layer for Tkinter to support old plugins, but the preferred toolkit for new plguins is PyQt5.
Before Version 126.96.36.199
Before PyMOL's Plugin Manager was added in version 188.8.131.52, plugins could not be installed per user, the plugin search path was a single directory inside the PyMOL installation: $PYMOL_PATH/modules/pmg_tk/startup
Plugins were limited to single Python files, directories were not supported yet.
MacPyMOL was the native macOS version of PyMOL before version 2.0. It supported Plugins only in the X11 Hybrid mode.
