Results

Top Level

Below are results that are in the base directory.

Filename Description
abricate.tsv A merged TSV file with Abricate results from all samples

Abricate

Below is a description of the per-sample results from Abricate.

Filename Description
<SAMPLE_NAME>.tzt A tab-delimited report of hits, for full details please see Abricate - Output

Audit Trail

Below are files that can assist you in understanding which parameters and program versions were used.

Logs

Each process that is executed will have a logs folder containing helpful files for you to review if the need ever arises.

Filename Description
nf-<PROCESS_NAME>.begin An empty file used to designate the process started
nf-<PROCESS_NAME>.err Contains STDERR outputs from the process
nf-<PROCESS_NAME>.log Contains both STDERR and STDOUT outputs from the process
nf-<PROCESS_NAME>.out Contains STDOUT outputs from the process
nf-<PROCESS_NAME>.run The script Nextflow uses to stage/unstage files and queue processes based on given profile
nf-<PROCESS_NAME>.sh The script executed by bash for the process
nf-<PROCESS_NAME>.trace The Nextflow Trace report for the process
versions.yml A YAML formatted file with program versions

Nextflow Reports

These Nextflow reports provide great a great summary of your run. These can be used to optimize resource usage and estimate expected costs if using cloud platforms.

Filename Description
abricate-dag.dot The Nextflow DAG visualisation
abricate-report.html The Nextflow Execution Report
abricate-timeline.html The Nextflow Timeline Report
abricate-trace.txt The Nextflow Trace report

Program Versions

At the end of each run, each of the versions.yml files are merged into the files below.

Filename Description
software_versions.yml A complete list of programs and versions used by each process
software_versions_mqc.yml A complete list of programs and versions formatted for MultiQC

Parameters

Required Parameters

Filtering Parameters

Use these parameters to specify which samples to include or exclude.

Parameter Description Default
--include A text file containing sample names (one per line) to include from the analysis
--exclude A text file containing sample names (one per line) to exclude from the analysis

Abricate Parameters

Parameter Description Default
--abricate_db Database to use ncbi
--minid Minimum DNA percent identity 80
--mincov Minimum DNA percent coverage 80

Optional Parameters

These optional parameters can be useful in certain settings.

Parameter Description Default
--outdir Base directory to write results to ./
--run_name Name of the directory to hold results bactopia
--skip_compression Ouput files will not be compressed False
--keep_all_files Keeps all analysis files created False

Max Job Request Parameters

Set the top limit for requested resources for any single job.

Parameter Description Default
--max_retry Maximum times to retry a process before allowing it to fail. 3
--max_cpus Maximum number of CPUs that can be requested for any single job. 4
--max_memory Maximum amount of memory (in GB) that can be requested for any single job. 32
--max_time Maximum amount of time (in minutes) that can be requested for any single job. 120
--max_downloads Maximum number of samples to download at a time 3

Nextflow Configuration Parameters

Parameters to fine-tune your Nextflow setup.

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

Nextflow Profile Parameters

Parameters to fine-tune your Nextflow setup.

Parameter Description Default
--condadir Directory to Nextflow should use for Conda environments
--registry Docker registry to pull containers from. dockerhub
--singularity_cache Directory where remote Singularity images are stored.
--singularity_pull_docker_container Instead of directly downloading Singularity images for use with Singularity, force the workflow to pull and convert Docker containers instead.
--force_rebuild Force overwrite of existing pre-built environments. False
--queue Comma-separated name of the queue(s) to be used by a job scheduler (e.g. AWS Batch or SLURM) general,high-memory
