GADMA

Welcome to GADMA v2!

GADMA implements methods for automatic inference of the joint demographic history of multiple populations from the genetic data.

GADMA is a command-line tool. Basic pipeline presents a series of launches of the global search algorithm followed by the local search optimization.

GADMA provides two types of demographic inference: 1) for user-specified model of demographic history or a custom model, 2) automatic inference for the model with specified structure (up to three populations, see more here).

GADMA provides choice of several engines of demographic inference. This list will be extended in the future. Available engines and maximum number of supported populations for custom model:

• ∂a∂i (up to 5 populations)
• moments (up to 5 populations)
• momi2 (up to ∞ populations)
• momentsLD - extenstion of moments (up to 5 populations)

More information about engines see here.

GADMA features various optimization methods (global and local search algorithms) which may be used for any general optimization problem.

Two global search algorithms are supported in GADMA:

• Genetic algorithm — the most common choice of optimization,
• Bayesian optimization — for demographic inference with time-consuming evaluations, e.g. for four and five populations using moments or ∂a∂i.

GADMA is developed in Computer Technologies laboratory at ITMO University under the supervision of Vladimir Ulyantsev and Pavel Dobrynin. The principal maintainer is Ekaterina Noskova (ekaterina.e.noskova@gmail.com)

GADMA is now of version 2! See Changelog.
