Tags: staphylococcus-aureus assembly annotation amr mlst spa-typing agr-typing sccmec named-workflow

Comprehensive analysis pipeline for Staphylococcus aureus isolates.

This workflow performs complete bacterial analysis including quality control, assembly, annotation, antimicrobial resistance detection, MLST typing, and Staphylococcus-specific analysis using Spatyper, AgrVATE, SCCmecFinder, and StaphSCAN. It processes raw sequencing reads and produces a comprehensive genomic characterization for S. aureus isolates.

Usage

staphopia \
  --input samples.csv \
  --outdir results/

Nextflow:

Parameter	Type	Default	Description
--nfconfig	string		A Nextflow compatible config file for custom profiles, loaded last and will overwrite existing variables if set.
--publish_dir_mode	string	copy	Method used to save pipeline results to output directory. (choices: symlink, rellink, link, copy, copyNoFollow, move)
--infodir	string	${params.outdir}/pipeline_info	Directory to keep pipeline Nextflow logs and reports.
--force	boolean	false	Nextflow will overwrite existing output files.
--cleanup_workdir	boolean	false	After Bactopia is successfully executed, the work directory will be deleted.

Institutional config options

Parameters used to describe centralized config profiles. These should not be edited.

Parameter	Type	Default	Description
--custom_config_version	string	master	Git commit id for Institutional configs.
--custom_config_base	string	https://raw.githubusercontent.com/nf-core/configs/master	Base directory for Institutional configs.
--config_profile_name	string		Institutional config name.
--config_profile_description	string		Institutional config description.
--config_profile_contact	string		Institutional config contact information.
--config_profile_url	string		Institutional config URL link.

Nextflow Profile Parameters

Parameters to fine-tune your Nextflow setup.

Parameter	Type	Default	Description
--condadir	string		Directory to Nextflow should use for Conda environments
--registry	string	quay.io	Registry to pull Docker containers from.
--datasets_cache	string	<HOME>/.bactopia/datasets	Directory where downloaded datasets should be stored.
--singularity_cache	string		Directory where remote Singularity images are stored.
--singularity_pull_docker_container	boolean		Instead of directly downloading Singularity images for use with Singularity, force the workflow to pull and convert Docker containers instead.
--force_rebuild	boolean	false	Force overwrite of existing pre-built environments.
--queue	string	general,high-memory	Comma-separated name of the queue(s) to be used by a job scheduler (e.g. AWS Batch or SLURM)
--cluster_opts	string		Additional options to pass to the executor. (e.g. SLURM: '--account=my_acct_name'
--container_opts	string		Additional options to pass to Apptainer, Docker, or Singularity. (e.g. Singularity: '-D pwd'
--disable_scratch	boolean	false	All intermediate files created on worker nodes of will be transferred to the head node.
