Haptools: a toolkit for admixture and haplotype analysis.

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.
