项目历史

The project is tied to the 2017 Nature Methods paper by Patro, Duggal, Love, Irizarry, and Kingsford, which the official docs and README ask users to cite. The original C++ salmon line became a common bulk RNA-seq quantifier, with selective alignment becoming the default mapping strategy from the 1.0.0 line according to the legacy official documentation.

In 2026 the project released salmon 2.0, a from-scratch Rust rewrite. Official release notes say the rewrite kept the familiar `salmon index` to `salmon quant` to `quant.sf` workflow and downstream output formats while moving to a single portable binary and adding an alignment-free `--sketch` mode.

采用历史

salmon is packaged across multiple package-manager ecosystems in the supplied package facts, including Homebrew, Debian, Ubuntu, and Nix. The official installation docs also document install-script binaries, Cargo, conda/Bioconda, Docker Hub, and GHCR images, reflecting its use in reproducible computational-biology pipelines.

The official docs describe `quant.sf` as directly readable by tximport, tximeta, fishpond, and swish, which is why salmon appears frequently in RNA-seq analysis workflows as a quantification stage rather than as a standalone end-user application.

使用方式

Typical use is to build an index from transcript FASTA input, quantify single-end or paired-end FASTQ reads against that index, and read transcript-level abundance estimates from `quant.sf`. The CLI also supports transcriptome BAM input, RAD input, bias correction flags, bootstraps or Gibbs samples for uncertainty, gene-level output via a transcript-to-gene map, and `quantmerge` for combining columns across samples.

为什么软件包爱好者会关心

salmon matters to package maintainers because it sits at the intersection of scientific CLI distribution and performance-sensitive native code. The 2.x Rust rewrite reduced the historic C++ dependency burden while preserving command names and output files, which makes package upgrades easier but still requires users to rebuild old C++ indices.

• Official docs name tximport, tximeta, fishpond, and swish as downstream tools that consume salmon output. They also point users of the removed historical `salmon alevin` single-cell workflow to the alevin-fry ecosystem.
