graphtyper-2.7.5

graphtyper is a graph-based variant caller capable of genotyping population-scale short read data sets. It represents a reference genome and known variants of a genomic region using an acyclic graph structure (a “pangenome reference”), which high-throughput sequence reads are re-aligned to for the purpose of discovering and genotyping SNPs, small indels, and structural variants.

Usage

The recommended way of genotyping small variants (SNP+indels) is using the genotype subcommand

1
./graphtyper genotype <REFERENCE.fa> --sams=<BAMLIST_OR_CRAMLIST> --region=<chrA:begin-end> --threads=<T>

and use the genotype_sv subcommand for genotyping structural variants

1
./graphtyper genotype_sv <REFERENCE.fa> <input.vcf.gz> --sams=<BAMLIST_OR_CRAMLIST> --region=<chrA:begin-end> --threads=<T>

See the graphtyper user guide for more details.
