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 0.4 has been released on 2013/12/20.
The latest version includes the OnePopVarSize
model, a model of variable population size for a single population; and
it can fit data under a generalized stepwise mutmation model (GSM) for
this demographic scenario. Thus 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., in press).
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.
The distribution now includes an R package (Rmigraine). The Ckrigcoefs library found in the previous distributions is now obsolete.

Current developments: models of variable population size and of population divergence; infinite site model and SNPs.
