BEAGLE is a state of the art software package for analysis of large-scale genetic data sets with hundreds of thousands of markers genotyped on thousands of samples. BEAGLE can

Beagle can also be used in conjunction with PRESTO, a program for fast and flexible permutation testing. PRESTO can compute empirical distributions of order statistics, analyze stratified data, and determine significance levels for one-stage and two-stage genetic association studies.

BEAGLE is written in Java and runs on any computing platform with a Java version 1.6 interpreter (e.g. Windows, Unix, Linux, Solaris, Mac).

Utility Programs

The BEAGLE Utilities web site has a number of utility programs that can be used to prepare input files and process output files.

When using multiple Beagle input files, the alleles for a marker must be on the same chromosome strand in each input file. Sharon Browning has written a python script that checks that alleles are defined with respect to the same chromosome strand and switches alleles if necessary to make the chromosome strands consistent. Click here to download Sharon's strand-checking utility.

Sharon Browning has written some utilities for processing output files from BEAGLE HBD/IBD analysis. Click here to download Sharon's HBD/IBD utilities.

When dealing with large sample sizes, it might be necessary to divide a sample so that imputation can be performed in each subsample separately. Click here to download a simple shell script for dividing your sample.

Two specialized programs, pseudomarker.jar and cluster2haps.jar are described in the BEAGLE documentation, and may be useful to some users:
