mPopTag: The Multi-Population Tag SNP Picker

Developed by:

The Multi-Population Tag Single Nucleotide Polymorphism (SNP) Picker (mPopTag) is a tool used to select or evaluate linkage disequilibrium (LD) tag SNPs for multiple populations. The program analyzes patterns of LD--measured by composite linkage disequilibrium (CLD) or r2--between polymorphic sites in a genome region for multiple populations. It also uses a greedy algorithm to select a single set of near-minimum numbers of LD tag SNPs for multiple populations.



The mPopTag was developed in and is maintained at the by Zongli Xu, Norman L. Kaplan and Jack A Taylor.

It can be run on Linux operating system.
