An ancestry server providing a local ancestry inference service for academics on high-throughput genome data (genotypes or haplotypes) using the aMAP pipeline


 An novel approach (aMAP, ancestry of Modern Admixed Populations) for inferring local phased ancestry

Ma Y, Zhao J, Wong JS, Ma L, Li W, Fu G, Xu W, Zhang K, Kittles RA, Li Y, Song Q. Accurate inference of local phased ancestry of modern admixed populations. Scientific Reports. 2014 Jul 23;4:5800. PMID:25052506


This software draws ancestral analysis data into an image file with specified format and size using the Java graphical interface.


Determines the haplotypes of each person from unphased high-throughput genotypes in family pedigrees. This method features high accuracy, chromosome-range phasing distance, linear computing, flexible pedigree types and flexible genetic marker types.

Using limited experimental seed data, HiFi can yield two integral, high-resolution personal chromosomal haplotypes in a cost- and time-efficient manner.
