Welcome to the JLOH documentation

What is JLOH?

JLOH (/jay’lo/) is a tool to extract, filter, and analyse loss of heterozygosity (LOH) blocks based on single-nucleotide polymorphisms (VCF), read mapping information (BAM), and a reference genome sequence (FASTA).

A publication is currently being reviewed. The preprint can be found in bioRxiv (Schiavinato et al., 2023).
