Migraine distribution page
Migraine implements coalescent algorithms for maximum likelihood analysis of population genetic data. The data currently handled are allelic counts but sequences will be handled in the forthcoming version. The code is designed to be compiled with the GNU C++ compiler under Windows and Linux (including its Mac OSX incarnation).
Recent changes (version 0.5): Migraine now includes a new 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.
Older changes: Version 0.4.1 corrected a major bug introduced for isolation by distance in the previous update (0.4.0.1, Feb 20).
The different models that can
be fit are:
- 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; infinite site model and SNPs.
