Results

Merged Results

Below are results that are concatenated into a single file.

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>.txt 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 folder named logs. In this folder are helpful files for you to review if the need ever arises.

Extension Description
.begin An empty file used to designate the process started
.err Contains STDERR outputs from the process
.log Contains both STDERR and STDOUT outputs from the process
.out Contains STDOUT outputs from the process
.run The script Nextflow uses to stage/unstage files and queue processes based on given profile
.sh The script executed by bash for the process
.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
