Bactopia Tool - `kleborate`¶

The kleborate module uses Kleborate to screen genome assemblies of Klebsiella pneumoniae and the Klebsiella pneumoniae species complex (KpSC). Kleborate predicts:

MLST, species,
ICEKp associated virulence loci
virulence plasmid associated loci
antimicrobial resistance determinants,
K (capsule) and O antigen (LPS) serotype prediction.

Example Usage¶

bactopia --wf kleborate \
  --bactopia /path/to/your/bactopia/results

Output Overview¶

Below is the default output structure for the kleborate tool. Where possible the file descriptions below were modified from a tools description.

Directory structure might be different

kleborate is available as a standalone Bactopia Tool, as well as from the main Bactopia workflow (e.g. through Staphopia or Merlin). If executed from Bactopia, the kleborate directory structure might be different, but the output descriptions below still apply.

Results¶

Merged Results¶

Below are results that are concatenated into a single file.

Filename	Description
kleborate.tsv	A tab-delimited file with `Kleborate` results from all samples

Kleborate¶

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

Filename	Description
<SAMPLE_NAME>.txt	A tab-delimited file with `Kleborate` result, see Kleborate - Example output for more details.

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
kleborate-dag.dot	The Nextflow DAG visualisation
kleborate-report.html	The Nextflow Execution Report
kleborate-timeline.html	The Nextflow Timeline Report
kleborate-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
