Deployment

Step 1: Install Snakemake and Snakedeploy

Snakemake and Snakedeploy are best installed via the Mamba package manager (a drop-in replacement for conda). If you have neither Conda nor Mamba, it is recommended to install Miniforge. More details regarding Mamba can be found here.

When using Mamba, run

mamba create -c conda-forge -c bioconda --name snakemake snakemake snakedeploy

to install both Snakemake and Snakedeploy in an isolated environment. For all following commands ensure that this environment is activated via

conda activate snakemake

Step 2: Deploy workflow

With Snakemake and Snakedeploy installed, the workflow can be deployed as follows. First, create an appropriate project working directory on your system and enter it:

mkdir -p path/to/project-workdir
cd path/to/project-workdir

In all following steps, we will assume that you are inside of that directory. Then run

snakedeploy deploy-workflow https://github.com/KonstantinBurkin/cbai . --tag None

Snakedeploy will create two folders, workflow and config. The former contains the deployment of the chosen workflow as a Snakemake module, the latter contains configuration files which will be modified in the next step in order to configure the workflow to your needs.

Step 3: Configure workflow

To configure the workflow, adapt config/config.yml to your needs following the instructions below.

Step 4: Run workflow

The deployment method is controlled using the --software-deployment-method (short --sdm) argument.

To run the workflow with automatic deployment of all required software via conda/mamba, use

snakemake --cores all --sdm conda

Snakemake will automatically detect the main Snakefile in the workflow subfolder and execute the workflow module that has been defined by the deployment in step 2.

For further options such as cluster and cloud execution, see the docs.

Step 5: Generate report

After finalizing your data analysis, you can automatically generate an interactive visual HTML report for inspection of results together with parameters and code inside of the browser using

snakemake --report report.zip

Configuration

The following section is imported from the workflow’s config/README.md.

General settings

To configure this workflow, modify config/config.yaml according to your needs, following the explanations provided in the file.

Sample and unit sheet

  • Add samples to config/samples.tsv. Only the column sample is mandatory, but any additional columns can be added.
  • For each sample, add one or more sequencing units (runs, lanes or replicates) to the unit sheet config/units.tsv. For each unit, define platform, and either one (column fq1) or two (columns fq1, fq2) FASTQ files (these can point to anywhere in your system).

The pipeline will jointly call all samples that are defined, following the GATK best practices.

 8Lints for rule minimap_index (line 217, /tmp/tmpec9g10io/workflow/rules/ref.smk):
 9    * No log directive defined:
10      Without a log directive, all output will be printed to the terminal. In
11      distributed environments, this means that errors are harder to discover.
12      In local environments, output of concurrent jobs will be mixed and become
13      unreadable.

17Lints for rule multiqc (line 50, /tmp/tmpec9g10io/workflow/rules/qc.smk):
18    * Migrate long run directives into scripts or notebooks:
19      Long run directives hamper workflow readability. Use the script or
20      notebook direcive instead. Note that the script or notebook directive does
21      not involve boilerplate. Similar to run, you will have direct access to
22      params, input, output, and wildcards.Only use the run direcive for a
23      handful of lines.
