Pymolrc

2013-01-30T18:47:01Z

Natechols:

When Pymol [[Launching PyMOL|launches]], it will read custom settings and functions from a .pymolrc (windows: pymolrc.pym) file.

In windows put file under "C:\Users\YOU\pymolrc.pym". 
On a Unix/Linux-type system (including Mac OS X), this file will be located in /path/to/home/.pymolrc.

An example of a .pymolrc file is:

<source lang="python">
# this will run the script in the specified location
run /path/to/home/pymol/load_sep.py

set movie_loop, 0
set two_sided_lighting, 1

set label_size, 60
set label_outline_color, 1
set label_color, 0
set label_position, [0, 0, 10]

# for images:
# antialias =1 smooths jagged edges, 0 turns it off
set antialias = 1

# stick_radius -adjust thickness of atomic bonds
set stick_radius = 0.3

# set fetch_path
set fetch_path, /your/fetch/path

</source>

To reload .pymolrc file (e.g. after editing .pymolrc, or after running [[reinitialize|reinitialize]]), use:

<source lang="python">
@~/.pymolrc
</source>

XML-RPC server

2012-01-23T22:06:52Z

Natechols:

PyMOL includes a built-in XML-RPC server which can be started from the command line (modules/pymol/rpc.py in the source code). This allows remote programs (not necessarily on the same computer) to connect and call functions in the running PyMOL instance. Starting the server is simple:

<source lang="bash">
pymol -R
</source>

Access to the XML-RPC server is independent of PyMOL itself, so the client could be run from any Python program, not necessarily on the same computer. The simple example below shows how the client code might be written.

<source lang="python">
from xmlrpclib import ServerProxy
pymol = ServerProxy(uri="http://localhost:9123/RPC2")
pymol.load("model.pdb")
</source>

= A more advanced server =

The main limitation of the built-in XML-RPC extension is that it requires all functions to be explicitly wrapped to be accessible via XML-RPC calls, which limits the flexibility. (It also appears to limit what custom methods can be wrapped.) An alternate design shown below will enable any method in the 'cmd' module to be called remotely, as well as custom methods of the "pymol_interface" class (several examples of which are shown below). Other modules (such as util) could be wrapped using the same trick.

The corresponding client code is shown below; not surprisingly, it is very simple to the example above. Because of the use of getattr() to retrieve methods in the 'cmd' API, we do not need to explicitly wrap cmd.load(), cmd.show(), or cmd.hide() for this code to work, and any other method in 'cmd' can be similarly accessed, as well as our custom methods.

<source lang="python">

pymol = ServerProxy(uri="http://localhost:9123/RPC2")
pymol.load("model.pdb")

Natechols:

* [[FilterByMol]] -- Filter a directory of files, and save their ligands to disk (by molecule).
* [[LoadDir]] -- loads all the files of a type you specify from the path you specify and puts them into the group you specify (or none).
* [[Process_All_Files_In_Directory]] -- Do something to all files in a directory. The examples show how to print the disulfide bond lengths, then in general all sulfur distances (not necessarily bound).
* [[PythonTerminal]] -- Allows execution of python commands from the PyMOL command line.
* [[pdbsurvey]] -- Surveys the pdb for recently added structures that are relevant to a user-specified keywords list (in a text file)
* [[Read PDB-String]] -- Parses a string in PDB format to a PyMOL object.
* [[Monitor file continuously]] -- Watch a file on a separate thread and re-load when it is modified.
* [[XML-RPC server]] -- An API for controlling PyMOL remotely (from the same computer or on the network). Adapted from the server built in to PyMOL.

= PyMOL-created Journal Covers =
Part of PyMOL's popularity comes from the fact that it is very flexible and it offers arbitrarily high-resolution images as output; this make it a great tool for making journal covers or any press-related images.

Here are some of the known PyMOL-created Journal Covers. There are surely more out there. If you have a cover you'd like to add, feel free.
