Bactopia Tool - `mobsuite`¶

The mobsuite module uses MOB-suite to reconstruct and annotate plasmids in draft assemblies.

Example Usage¶

bactopia --wf mobsuite \
  --bactopia /path/to/your/bactopia/results \ 
  --include includes.txt

Output Overview¶

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

Results¶

Merged Results¶

Below are results that are concatenated into a single file.

Filename	Description
mobsuite.tsv	A merged TSV file with `mobsuite` results from all samples

MOB-suite¶

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

Filename	Description
<SAMPLE_NAME>-mobtyper.txt	Aggregate MOB-typer report files for all identified plasmid, see MOB-typer - report file for more details
chromosome.fasta	FASTA file of all contigs found to belong to the chromosome
contig_report.txt	Assignment of the contig to chromosome or a particular plasmid grouping, see MOB-recon - contig report for more details
plasmid_<PLASMID_NAME>.fasta	Each plasmid group is written to an individual FASTA

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