## Project history and usage

Spoa is a C++ SIMD implementation of partial order alignment, packaged as both a command-line tool and library for generating consensus sequences from biological sequence reads.

### Project history

The official README defines Spoa as `SIMD POA`, an implementation of the partial order alignment algorithm used to generate consensus sequences. It supports local, global, and semi-global alignment modes, linear, affine, and convex gap modes, and SIMD acceleration through SSE4.1+, AVX2, SIMDe, and dispatching.

Spoa is tied to the long-read sequencing era: the README points to the original POA and consensus-sequence literature, while the project is also marked as published in Genome Research. In package form, it gives bioinformatics pipelines a small native executable and a linkable library rather than a large workflow framework.

### Adoption history

The supplied package-manager data lists Spoa in Homebrew and as `libspoa-dev` in Debian and Ubuntu. That packaging split reflects its dual role: command for direct FASTA/FASTQ processing and development library for other genomics tools.

### How it is used

The `spoa` command reads FASTA or FASTQ sequences, including gzip-compressed input, and writes consensus or multiple-sequence-alignment FASTA output. Options select scoring, gap penalties, alignment mode, and result mode.

### Why package nerds care

Spoa matters to package maintainers because it is a compact, performance-sensitive C++ bioinformatics dependency. Its optional SIMD/SIMDe paths and library install targets are exactly the kind of details that determine whether a formula or distro package is useful beyond a single architecture.

### Timeline

- 2002: Partial order alignment is published in Bioinformatics, the algorithmic foundation cited by the Spoa README.
- 2003: Consensus sequence generation with partial order graphs is published, also cited by the Spoa README.
- 2017: Spoa is associated with a Genome Research publication badge in the official repository.
- Ongoing: The README documents CMake and Meson builds plus SIMD and portability options.

### Related projects

- The original POA algorithm and consensus-sequence papers are cited by the official Spoa README.
- SIMDe is listed as a portability option for SIMD support.
- bioparser and biosoup are listed as dependencies for the executable and tests.
