Migraine distribution page
Migraine implements coalescent algorithms for maximum likelihood analysis of population genetic data. It considers Allelic counts and DNA sequences. The code is designed to be compiled with the GNU C++ compiler under Windows and Linux (including its Mac OSX incarnation).
Recent changes (from version 0.5 upwards): Migraine now includes the Infinite Site Mutation (ISM) model, a new demographic model, OnePopFounderFlush, and a resampling procedure improving the importance sampling algorithm in the OnePopVarSize model. Further, it now uses a standard R package, blackbox, rather than the older Rmigraine package that was previously distributed through this page, so that installation is easier.
The different models that can be fitted
- one- and two-dimensional isolation by distance models (including the island model as a subcase) (Rousset and Leblois 2007,2012);
- the two-populations model described in de Iorio et al. (2005);
- the elementary one-population model (with 2Nμ as unique parameter);
- the OnePopVarSize model, including markers evolving under a GSM (Leblois et al., 2014) or an ISM;
- the OnePopFounderFlush model.
Typical analyses can be performed in seconds (in the one-parameter case) or overnight (in some three-parameter cases), and longer analyses can easily been split among different computers.

Current developments: models of variable population size and of population divergence, and SNPs.
