DISCLAIMER: This page was originally developed for the 2008 Google Summer of Code competition and is kept only for historical reasons. If you want to discuss an idea or feature implementation just send and e-mail to the PyMOL_mailing_list. If you want to request a new feature or report a bug, please fill a ticket at sourceforge



Ideas for PyMOL Development

Where to Start

Always start with Python and only delve down into the C code when absolutely necessary. Although PyMOL is mostly a C-based application, much of the that code is opaque, fragile, and unforgiving. Although C code refactoring is an important project goal, such work may not be ideal since once mistake could potentially to destabilize the entire platform.

Fortunately, the Python interpreter and the PyMOL command and selection languages make it possible to extend PyMOL safely and quickly. Even when performance is critical, Python should be the interface between external C, C++, and Java code and PyMOL's internal C data structures.

Choosing a Topic

The best open-source code is usually written by an end-users attempting to meet their own pressing needs. So if you have already have a specific need which relates to PyMOL, then we strongly encourage you to follow up on that first!

If you are looking for ideas, then try to seek out enhancements and/or integrations that will impact the largest potential user base. For example, imagine what new things might be useful to virtually all medicinal chemists, all structural biologists, all movie-makers, all paper-writers, and so forth.

The ideas below are organized by category. Right now, integration with other open-source projects seems like the approach most likely to yield significant benefit, so those ideas are first.

Integration Ideas (Linking Out to Useful Open-Source Tools)

In most cases, depending on the need, integration can be accomplished through standalone Python scripts, through new PyMOL commands, through PyMOL Wizards, or via Tkinter plugins.

  • APBS (electrostatics calculations): Improve the existing plugin. Michael Lerner is currently leading this effort. See APBS

Are there other key open-source packages we might specifically target for integration with PyMOL, either through GSoC or beyond?

Low-Level Enhancement Ideas (Mostly C-oriented)

Ideas Involving Proprietary APIs

Since these involve closed-source APIs and infrastructure, they aren't suitable for open-source development efforts. However, such requests are noted here for the sake of complete coverage.

  • Create a Windows port with "native" look & feel. <- Could this be done in PyQT or PyGTK?. Then it would look "native", but be cross-platform and not proprietary.

Ideas for Plugin Developers

The range of things that PyMOL plugins can do has grown by leaps and bounds over the last several years. It may be time for some new infrastructure to facilitate plugin development.

  • Plugins that span multiple files. This means 1. the ability to have them 2. the ability for users to easily install them.
yea (1) / nay (0) (Michael Lerner)
  • Config files that persist between sessions. This would be useful for things like remembering the locations of external programs, etc., without requiring the user to modify their .pymolrc.
yea (1) / nay (0) (Michael Lerner)
  • Restart PyMOL. After installing a plugin, PyMOL needs to be restarted to use the plugin. This is tedious when testing plugins under development.

More Ideas (Please add your own!)

  • I often need to "replicate" previously PyMOL-made figures using newer coordinates/structures. It would be a big help (to me), if PyMOL could produce an exported text file from the old PyMOL .pse file of graphical settings that I could then modify and apply as a pymol script to the new structure -- I'm thinking of something like an old-style MOLSCRIPT.INP file...

  • MolViz is a project to incorporate head tracking input into PyMol. This is accomplished through a ImmersiveViz script written in Python to control the molecule's position using the existing PyMol API. Related projects would include:
    • Improving the existing ImmersiveViz PyMol plugin for more precise control of the environment.
    • Developing new input drivers for the Wiimote form of control. This would require some bluetooth hacking.
    • Implementing some other forms of input for head tracking, such as fisheye head tracking, IR webcam tracking, etc (refer to the end of this [video] for a better description).
