SeqDesk · original analysis
Citation adoption for curated taxonomic profiling & classification tools, counted weekly from OpenAlex.
Software health, not citations: GitHub/GitLab stars and last-commit date for each tool’s canonical source repo, as a point-in-time snapshot (2026-06-30). Bars in the last-commit chart show how recently each repo was touched — active, stale, archived or gone. Star bars are tinted to match each tool’s citation line above.
Use cumulative view for long-run adoption and annual view for citation momentum; log scale makes smaller tools readable without changing the counts. Counts are annual OpenAlex cited-by tallies and reflect all uses of each paper, not only use inside the selected workflow; broad tools can therefore look larger than workflow-specific methods. The still-filling current year (2026) is omitted from the lines.
Each dot is one of 22 curated tools with a datable code repository (0 web-only / SourceForge tools without a public commit date aren't shown). Higher means more cited in 2025, the latest complete year (log scale); further left means more recently updated (square-root scale). Filled dots are actively maintained — a commit within the last 18 months. The upper-left gathers the field's well-kept, widely-used staples: fastp, SAMtools, DADA2, SPAdes, Prokka, DIAMOND and more, updated regularly and cited thousands of times a year. Maintenance and citations are only loosely linked (Spearman ρ ≈ −0.46): a citation counts every paper that mentions a method, so a quieter commit history does not mean a tool is unused or unmaintained — many stable, widely-relied-on tools rarely need new commits, and development sometimes moves to mirrors this snapshot can't see.

The leading taxonomic profiling & classification tool is recomputed for each complete calendar year by cumulative citations — a 3-way hand-off across 14 years.
