chemlab is currently tested on Ubuntu 13.04 and python 2.7, it should work on 3.3 too. First install the dependencies:
$ sudo apt-get install python-numpy python-scipy python-matplotlib python-pyside python-opengl cython
Download unpack and install chemlab from the setup.py included in the package:
$ wget https://pypi.python.org/packages/source/c/chemlab/chemlab-0.3.tar.gz
$ tar xvzf chemlab-0.3.tar.gz
$ cd chemlab-0.3
$ sudo python setup.py build_ext --inplace
$ sudo python setup.py install
Test the newly installed package by typing:
$ chemlab view tests/data/cry.gro
The molecular viewer should display a crystal, if not, file an issue on github.
Once you’re setup, you’re ready to to dig in chemlab’s features. You may start from the User Manual.
After installing the dependencies, grab the chemlab source from git:
$ git clone --recursive https://github.com/chemlab/chemlab.git
Complile the included extensions:
$ python setup.py build_ext --inplace
Just add the chemlab directory to the PYTHONPATH in your .bashrc:
export PYTHONPATH=$PYTHONPATH:/path/to/chemlab
