Area of Science:

Genomics
Population Genetics
Bioinformatics

Background:

Genome-wide association studies (GWAS) and downstream analyses benefit from incorporating local ancestry and haplotype information, particularly for diverse and recently admixed populations.
Existing analytical frameworks often lack support for these features, focusing primarily on variant-level analysis.

Purpose of the Study:

To introduce haptools, an open-source toolkit for local ancestry-aware and haplotype-based analysis of complex traits.
To provide tools for enhanced genomic analysis in populations with admixed ancestries.

Main Methods:

Haptools offers fast simulation of admixed genomes.
It supports visualization of admixture tracks.
The toolkit enables simulation of haplotype- and local ancestry-specific phenotype effects and performs haplotype-aware file operations and statistics.

Main Results:

Haptools facilitates the integration of local ancestry and haplotype information into genomic analyses.
It addresses limitations of existing frameworks by providing specialized functionalities.
The toolkit supports a range of analyses crucial for understanding complex traits in admixed populations.

Conclusions:

Haptools enhances the utility of genomics for individuals from diverse and recently admixed ancestries.
The toolkit provides essential features for advanced haplotype-based and local ancestry-aware analyses.
Haptools represents a significant advancement for population genetics and complex trait research.
