HyRec

HyRec is a software tool designed for high-throughput sequencing data analysis. It focuses on the accurate and efficient processing of DNA sequencing reads, particularly for applications involving the study of hybrid genomes or populations with complex genetic structures. The primary function of HyRec is to facilitate the identification and separation of reads originating from different parental genomes within a hybrid or admixed sample.

This is achieved through a probabilistic approach that leverages differences in sequence composition, such as single nucleotide polymorphisms (SNPs) or other genetic markers, between the parental lineages. HyRec can be used in various stages of genomic analysis, including variant calling, genome assembly, and population genetics studies. Its ability to distinguish parental contributions is crucial for understanding phenomena like introgression, hybridization events, and the genetic makeup of hybrid species.

The software is typically command-line driven, making it suitable for integration into larger bioinformatics pipelines. It requires reference genomes of the parental species as input to guide the read assignment process. While primarily developed for specific applications, the underlying principles of HyRec can be adapted for other scenarios where distinguishing between closely related genetic sources is important. Researchers utilize HyRec to gain deeper insights into evolutionary processes and the genetic diversity within hybrid populations.
