Long-read sequencing technologies (PacBio HiFi, Oxford Nanopore) enable detection of structural variants, haplotype-resolved assembly, and repeat expansion genotyping that are inaccessible to short reads. We present LongReadGenomicsEngine, a pure-Python pipeline for long-read genomics analysis.

Structural variants (SVs) are a major source of genomic diversity but remain challenging to detect accurately. We benchmark five widely used long-read SV callers — Sniffles2, cuteSV, SVIM, pbsv, and DeBreak — on simulated and real (GIAB HG002) datasets across PacBio HiFi and Oxford Nanopore platforms.
