# Gmin Details

## Use

#### Gmin is intended to serve as a summary measure that identifies candidate gene flow regions which can then be examined in more detail. It is therefore useful to calculate Gmin in sliding windows then visually or statistically identify outliers. Due to the simplicity of the Gmin measure it can easily be calculated from any aligned sequence dataset drawn from two or more populations. The ability to calculate Gmin from BAM files has also been added to the population genomic software package POPBAM, using the haplo function.
