MACS logo INSTALL Guide for MACS

Please check the following instructions to complete your installation.


Python version must be equal to 2.6 or 2.7 to run MACS. We recommend using the version 2.6.5.

Install under Debian or Ubuntu Linux system

The most convenient way to install MACS is through Debian APT system, so that it can be perfectly integrated in the Python environment of your operation system. You can easily manage the package, and the uninstall is much easier. Download the deb package from MACS download page, and type this in the commend line:

$ dpkg -i macs_1.4.0.deb

To uninstall, type:

$ dpkg -r macs_1.4.0

This is tested only in Ubuntu 10.10 and 10.04 LTS.

Install from source

MACS uses Python's distutils tools for source installations. To install a source distribution of MACS, unpack the distribution tarball and open up a command terminal. Go to the directory where you unpacked MACS, and simply run the install script :

$ python install

By default, the script will install python library and executable codes globally, which means you need to be root or administrator of the machine so as to complete the installation. Please contact the administrator of that machine if you want their help. If you need to provide a nonstandard install prefix, or any other nonstandard options, you can provide many command line options to the install script. Use the –help option to see a brief list of available options:

$ python --help

For example, if I want to install everything under my own HOME directory, use this command:

$ python install --prefix /home/taoliu/

Configure enviroment variables

After running the setup script, you might need to add the install location to your PYTHONPATH and PATH environment variables. The process for doing this varies on each platform, but the general concept is the same across platforms.


To set up your PYTHONPATH environment variable, you'll need to add the value PREFIX/lib/pythonX.Y/site-packages to your existing PYTHONPATH. In this value, X.Y stands for the major–minor version of Python you are using (such as 2.6 or 2.7 ; you can find this with sys.version[:3] from a Python command line). PREFIX is the install prefix where you installed MACS. If you did not specify a prefix on the command line, MACS will be installed using Python's sys.prefix value.

On Linux, using bash, I include the new value in my PYTHONPATH by adding this line to my ~/.bashrc :

$ export PYTHONPATH=/home/taoliu/lib/python2.6/site-packages:$PYTHONPATH

Using Windows, you need to open up the system properties dialog, and locate the tab labeled Environment. Add your value to the PYTHONPATH variable, or create a new PYTHONPATH variable if there isn't one already.


Just like your PYTHONPATH, you'll also need to add a new value to your PATH environment variable so that you can use the MACS command line directly. Unlike the PYTHONPATH value, however, this time you'll need to add PREFIX/bin to your PATH environment variable. The process for updating this is the same as described above for the PYTHONPATH variable.

$ export PATH=/home/taoliu/bin:$PATH
