Lagrange is a Python package implementing likelihood models for geographic range evolution on phylogenetic trees, with methods for inferring rates of dispersal and local extinction and ancestral ranges.
This software implements methods described in Ree, R H and S A Smith. 2008. Maximum likelihood inference of geographic range evolution by dispersal, local extinction, and cladogenesis. Systematic Biology 57(1):4-14.
Analyses are run as Python scripts that use the Lagrange API. Update 23 March 2009: a web-based configuration tool is now available for testing at http://www.reelab.net/lagrange. This tool lets you configure and download your analysis as a Python script which is then run on your own computer. The script therefore requires you to install the latest snapshot release of Lagrange and its dependencies (see System Requirements below).
For help running Lagrange, contact Rick Ree or Stephen Smith.
System requirements
- Python 2.4 or newer
- Scipy - scientific libraries for python (and numpy - numerical libraries)
- for Debian Linux and derivatives, e.g. Ubuntu:
- for Mac OS X: see the InstallationMac page
- for Windows: installers available from Sourceforge
- The Enthought Python Distribution bundles scipy, numpy, and many other libraries and is available for Windows, Mac, and Linux
sudo apt-get install python-scipy
