| description | FastANI — alignment-free approximate mapping for high-throughput average nucleotide identity (ANI) among prokaryotic genomes/MAGs. Use when: (1) Reproducing literature that reports FastANI, (2) Pairwise/species-boundary ANI at moderate catalogue scales, (3) Comparing to skani for Methods. Upstream: https://github.com/ParBLiSS/FastANI. Prefer skani for very large MAG sets / incomplete genomes unless FastANI is required for compatibility.

Analytical thinking
FastANI popularized scalable ~95% ANI species-boundary analyses. Still widely
cited in Methods even when newer tools are faster.
| Tool | Prefer when |
|---|
skani | Large MAG catalogues; incomplete MAGs; speed/memory |
fastani | Compatibility with published FastANI thresholds / pipelines |
drep | Dereplication workflow (may call ANI backends) |
State the ANI tool + version + cutoff (commonly 95% species; AF/alignment
fraction matters — report it).
How to run
conda install -c bioconda fastani
fastani -q query.fa -r reference.fa -o temp/fastani/out.txt
