Run the built-in test set to confirm all parts are working as-expected. It will also download all dependencies to make subsequent runs much faster.
nextflow pull bacterial-genomics/wf-ani
nextflow run \
bacterial-genomics/wf-ani \
-r main \
-profile <docker|singularity>,test
Example command on FastAs in "new-fasta-dir" data using BLAST (ANIb) with singularity:
nextflow pull bacterial-genomics/wf-ani
nextflow run \
bacterial-genomics/wf-ani \
-r main \
-profile singularity \
--input new-fasta-dir \
--outdir my-results \
--ani blast
This workflow performs average nucleotide identity on assembled and/or annotated files (FastA/Genbank).
- Nextflow
>=22.04.03 - Docker or Singularity
>=3.8.0 - Conda is currently unsupported
nextflow run main.nf -profile <docker|singularity> --input <input directory> --outdir <directory for results> --ani <blast|fastani|skani>
Please see the usage documentation for further information on using this workflow.
Note the "--" long name arguments (e.g., --help, --input, --outdir) are generally specific to this workflow's options, whereas "-" long name options (e.g., -help, -latest, -profile) are general nextflow options.
These are the most pertinent options for this workflow:
============================================
Input/Output
============================================
--input Path to input data directory containing FastA/Genbank assemblies or samplesheet. Recognized extensions are: {fa,fas,fsa,fna,fasta,gb,gbk,gbf,gbff} with optional gzip compression.
--query Path to input data FastA/Genbank file or samplesheet. Recognized extensions are: {fa,fas,fsa,fna,fasta,gb,gbk,gbf,gbff} with optional gzip compression.
--refdir Path to reference panel data directory containing FastA/Genbank assemblies or samplesheet. Recognized extensions are: {fa,fas,fsa,fna,fasta,gb,gbk,gbf,gbff} with optional gzip compression.
--outdir The output directory where the results will be saved.
============================================
Container platforms
============================================
-profile singularity Use Singularity images to run the workflow. Will pull and convert Docker images from Dockerhub if not locally available.
-profile docker Use Docker images to run the workflow. Will pull images from Dockerhub if not locally available.
============================================
Optional ANI tools
============================================
--ani Specify what algorithm should be used to compare input files. Recognized arguments are: blast, fastani, skani. [Default: blast]

The most well-tested and supported is a Univa Grid Engine (UGE) job scheduler with Singularity for dependency handling.
- UGE/SGE
- Additional tips for UGE processing are here.
- No Scheduler
- It has also been confirmed to work on desktop and laptop environments without a job scheduler using Docker with more tips here.
Please see the output documentation for a table of all outputs created by this workflow.
Q: It failed, how do I find out what went wrong?
A: View file contents in the <outdir>/log directory.
