Nextflow run with conda ❌ run with docker run with singularity Launch on Seqera Platform

Introduction

plant-food-research-open/assemblyqc is a Nextflow pipeline which evaluates assembly quality with multiple QC tools and presents the results in a unified html report. The tools are shown in the Pipeline Flowchart and their references are listed in CITATIONS.md.

Usage

Refer to usage, parameters and output documents for details.

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.

Prepare an assemblysheet.csv file with following columns representing target assemblies and associated meta-data.

  • tag: A unique tag which represents the target assembly throughout the pipeline and in the final report
  • fasta: FASTA file

Now, you can run the pipeline using:

nextflow run plant-food-research-open/assemblyqc \
   -profile <docker/singularity/.../institute> \
   --input assemblysheet.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.

Plant&Food Users

Download the pipeline to your /workspace/$USER folder. Change the parameters defined in the pfr/params.json file. Submit the pipeline to SLURM for execution.
