  TwinStrand Biosciences ships no API client library or SDK — it publishes no product API to
  wrap. Registries probed 2026-08-05 with no first-party hit for "twinstrand", "twinstrandbio"
  or "duplexseq": npm, PyPI, Maven Central, NuGet, pkg.go.dev, RubyGems, Packagist, crates.io.
  The DuplexSeq analysis pipeline is delivered as cloud software on the DNAnexus platform, not as
  an installable package. The github.com/twinstrandbio organization holds exactly one public
  repository (reference data, not code); a second organization, github.com/twinstrandbio-analytics
  ("Computational analysis projects at TwinStrand"), exists but has zero public repositories.
  Third-party packages named "duplexseq" on GitHub (dbsloan/duplexseq, jfnavarro/duplexseq,
  sudmantlab/DuplexSequencingPipeline, the makovalab-psu duplex-sequencing repos) are academic
  reimplementations of the published method and are NOT TwinStrand artifacts — they are recorded
  here only so a later round does not mistake them for first-party.

  description: >-
    The only public repository in the TwinStrand Biosciences GitHub organization. It publishes
    reference data for the DuplexSeq assays — an `interval-sets` directory of genomic target
    regions — under a BSD 3-Clause Clear license. It is data, not a client library, and is not
    distributed through any package registry.
