Introduction

The nf-core/rnadnavar is a bioinformatics best-practice analysis pipeline for Pipeline for RNA and DNA integrated analysis for somatic mutation detection.

Initially designed for cancer research, the pipeline
uses different variant calling algorithms and applies a consensus approach. A final filtering stage, should provide a set of annotated somatic variants.

The pipeline is built using Nextflow, a workflow tool to run tasks across multiple compute infrastructures in a very portable manner. It uses Docker/Singularity containers making installation trivial and results highly reproducible. The Nextflow DSL2 implementation of this pipeline uses one container per process which makes it much easier to maintain and update software dependencies. Where possible, these processes have been submitted to and installed from nf-core/modules in order to make them available to all nf-core pipelines, and to everyone within the Nextflow community!

Pipeline summary

  1. Read QC (FastQC)
  2. Present QC for raw reads (MultiQC)
  3. Alignment (BWA/STAR)
  4. GATK pre-processing
  5. Variant calling
  6. Normalise calls
  7. Annotation
  8. Consensus
  9. Filtering
  10. Realignment [OPT]
  11. RNA filtering

Usage

Note If you are new to Nextflow and nf-core, please refer to this page on how to set-up Nextflow. Make sure to test your setup with -profile test before running the workflow on actual data.

Now, you can run the pipeline using:

nextflow run nf-core/rnadnavar \
   -profile <docker/singularity/.../institute> \
   --input samplesheet.csv \
   --outdir <OUTDIR>

Warning: Please provide pipeline parameters via the CLI or Nextflow -params-file option. Custom config files including those provided by the -c Nextflow option can be used to provide any configuration except for parameters; see docs.

For more details and further functionality, please refer to the usage documentation and the parameter documentation.

Pipeline output

To see the results of an example test run with a full size dataset refer to the results tab on the nf-core website pipeline page. For more details about the output files and reports, please refer to the output documentation.
