OrthoANIu tool
Welcome to OrthoANIu tool, a standalone average nucleotide identity (ANI) calculator, which uses the improved ANI algorithm (OrthoANI) with USEARCH.

Overview

Although ANI is widely used to classify and identify bacteria, OrthoANI (Lee et al. 2015) was developed to overcome the large differences in reciprocal ANI values associated with the ANI algorithm. Furthermore, OrthoANIu tool employees USEARCH over BLAST for its OrthoANI calculations which increases the number of comparative studies and substantially decrease computational time. [Learn more]

Input

Genome FASTA files.

Output

Print results to stdout are in tabbed key-value pairs.

Requirements

  • Java Runtime Environment Version 8 (Java Download)
  • USEARCH (32-bit Download)
    *Although 64-bit version will reduce overall process time, we concluded that it is sufficient to use 32-bit version for a small number of genomes.
