Revision as of 12:41, 15 October 2012

My name is Thomas Holder and I am a bioinformatician at the MPI for Developmental Biology in Tübingen, Germany.

I was awarded the Warren L. DeLano Memorial PyMOL Open-Source Fellowship for 2011-2012.

Scripts written by me

Scripts Pastebin

Some random scripts with no dedicated PyMOLWiki page.

Launch interactive python terminal with PyMOL process: (see also Launching From a Script)

#!/usr/bin/python2.6 -i

import sys, os

# autocompletion
import readline
import rlcompleter
readline.parse_and_bind('tab: complete')

# pymol environment
moddir='/opt/pymol-svn/modules'
sys.path.insert(0, moddir)
os.putenv('PYMOL_PATH', os.path.join(moddir, 'pymol/pymol_path'))

# pymol launching
import pymol
pymol.pymol_argv = ['pymol','-qc'] + sys.argv[1:]
pymol.finish_launching()
cmd = pymol.cmd

Build PyMOL: (see also Linux Install)

#!/bin/bash -e

src=/tmp
prefix=/opt/pymol-git

pyinstall() {
    cd $src
    name=$(basename $2)
    
    if [[ -e $name ]]; then
        cd $name && $1 pull
    else
        $1 clone $2 && cd $name
    fi

    python setup.py build install \
        --home=$prefix \
        --install-lib=$prefix/modules \
        --install-scripts=$prefix
}

pyinstall git git@github.com:speleo3/pymol
pyinstall git git@github.com:speleo3/pymol-psico
pyinstall hg https://hg.codeplex.com/csb

Build FREEMOL (see also MovieSchool 6)

#!/bin/bash -e

src=/tmp
prefix=/opt/pymol-git
export FREEMOL=$prefix/freemol

freemoltrunk=$src/freemol-trunk
if [[ ! -e $freemoltrunk ]]; then
    svn co svn://bioinformatics.org/svnroot/freemol/trunk $freemoltrunk
fi

cd $freemoltrunk

sed -i 's/vdwtype\[11\]/vdwtype[14]/' src/mengine/src/field.h

for name in mpeg_encode mengine apbs pdb2pqr; do
    (cd src/$name && ./configure && make && make install)
done

cp -na freemol/libpy/freemol $prefix/modules/

ln -sfT $FREEMOL $prefix/modules/pymol/pymol_path/freemol

Download all PyMOL scripts from Robert L. Campbell's website:

Render movie from PNG files (save as png2mpeg1.sh):
