Obtaining and installing the program

This manual assumes that you already have MODELLER installed on your computer. Please refer to the MODELLER web site at http://salilab.org/modeller/ for information on obtaining and installing the program.

Please note that while MODELLER includes a Python interpreter, it does not include any of the standard Python modules. Most of the MODELLER scripts do not require these modules, but if you wish to write scripts which do use them, you will need to install these yourself, unless your system already has the correct version of Python installed:

For Windows

Use the Windows installer for Python 2.3.5, available at http://www.python.org/2.3.5/.

For Mac OS X 10.3 or 10.4 (Panther or Tiger)

MODELLER will use the standard system Python (2.3); no additional configuration is necessary.

For Mac OS X 10.2 (Jaguar)

MODELLER should work with the MacPython 2.3.3 distribution for OS X 10.2, available from http://homepages.cwi.nl/~jack/macpython/download.html.

For Linux with Python 2.3 (e.g. Fedora Core 3, Mandrake 10.1)

MODELLER will use the standard system Python (2.3.4); no additional configuration is necessary.

For Solaris

MODELLER works with the Python 2.3.3 package available at http://www.sunfreeware.com/.

Other Linux/Unix systems

You will need to build Python from the source code, available at the Python website. If you install it in a non-standard location (e.g. not /usr/local/python2.3 or /usr/lib/python2.3) then you will need to set the PYTHONHOME environment variable before starting MODELLER, so that it can find the modules.
