Download and install ASE

Requirements for ASE

The following packages are required for basiv ASE functionality:

  1. Python 2.2 or later is required. Python is available from
  2. Numeric Python. Use the latest version 24.2.
  3. Scientific Python from

The following packages are optional, since they enable the use of some specific external tools. You only need to install these tools if you want to use the extra tools mentioned:

  1. Rasmol from

    A rasmol src and binary rpm can be use for installing Rasmol on linux. You can run ASE without RasMol, you just won't be able to plot atoms with the RasMol plotter.

  1. Gnuplot. ASE can use Gnuplot via the Gnuplot-Python interface from At CAMP/Niflheim we call this RPM python-gnuplot.
  2. Python Pexpect from

    The current version of Pexpect is 2.1, but at Niflheim we use an old version 0.999. Both versions can be downloaded from the above site. At CAMP/Niflheim we install the Pexpect RPM under the name of python-pexpect.

  3. Matplotlib (Jens Jørgen ?).

Installation of a Python-based package

A Python-based package such as ASE or any of the above mentioned extra packages are usually downloaded as a tar-ball or from a CVS repository.

In order to install the package you have two options (both require superuser priviledges):

  1. Install as a Python package:

    python install
  2. Build an RPM package and install it on one or many machines:

    python bdist_rpm

    You have to locate the finished RPM package after building, it may be in the dist/ subdirectory if correctly implemented, or in another directory such as build/bdist.linux-x86_64/rpm/RPMS/ (for the x86_64 architecture).

If you don't have root permissions, you will need to add the package directory to your PYTHONPATH environment variable and use your local copy of the code.

Installation of ASE

The latest version of Campos ASE is version 2.3. Get the tar-ball here: campos-ase-2.3.4.tar.gz. For CVS access to the Campos ASE code see the Campos CVS page (simply cvs checkout CamposASE2).

Make sure that everything works by running the test suite:

cd ASE/Tests

To get started with Campos ASE, point your browser at the CamposASE homepage.
