## Project history and usage

oarfish is a Rust tool from COMBINE-lab for transcript-level quantification from long-read RNA-seq data, including Oxford Nanopore cDNA/direct RNA and PacBio reads. It allocates multi-mapping reads probabilistically with an expectation-maximization model and adds coverage information to improve isoform-level estimates.

### Project history

The GitHub repository was created on June 27, 2022. The project emerged from the COMBINE-lab lineage of RNA-seq quantification tools, applying probabilistic transcript-assignment ideas to long-read sequencing rather than short-read workflows.

### Adoption history

The method was described in the 2024 preprint and later Bioinformatics paper "Enhanced probabilistic modeling leads to improved accuracy in long-read transcriptome quantification." Distribution through GitHub releases, Cargo, Bioconda, and Homebrew made it available to both Rust users and bioinformatics workflow environments.

### How it is used

oarfish accepts transcriptome BAM alignments, raw reads that it maps internally, genome reads that are spliced-aligned and projected to transcripts, or existing genome BAMs projected against a transcript annotation. The common workflow is to supply long-read RNA-seq data plus transcript sequences or annotation, then produce transcript abundance estimates with optional bootstrap uncertainty and coverage modeling.

### Why package nerds care

For package watchers, oarfish is a good example of scientific software moving through several distribution channels at once: a Rust codebase and Cargo package, prebuilt GitHub release binaries, Bioconda recipes for workflow managers, and a Homebrew formula for local command-line installs.

### Timeline

- 2022-06-27: COMBINE-lab/oarfish repository was created.
- 2024-02-28: The oarfish preprint was posted to bioRxiv.
- 2026-06-07: GitHub release v0.10.0 was published.

### Related projects

- The documentation compares or connects oarfish with NanoCount-style filters, minimap2 and other aligners for BAM input, rammap for in-process long-read mapping, and bramble for genome-to-transcript projection.
