nf-core/epitopeprediction
A bioinformatics best-practice analysis pipeline for epitope prediction and annotation
2.3.0
). The latest
stable release is
2.3.1
.
Introduction
nf-core/epitopeprediction is a bioinformatics best-practice analysis pipeline for epitope prediction and annotation. The pipeline performs epitope predictions for a given set of variants or peptides directly using state of the art prediction tools. Additionally, resulting prediction results can be annotated with metadata.
Supported prediction tools:
syfpeithi
mhcflurry
mhcnuggets-class-1
mhcnuggets-class-2
netmhcpan-4.0
netmhcpan-4.1
netmhc-4.0
netmhciipan-4.1
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 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!
On release, automated continuous integration tests run the pipeline on a full-sized dataset on the AWS cloud infrastructure. This ensures that the pipeline runs on AWS, has sensible resource allocation defaults set to run on real-world datasets, and permits the persistent storage of results to benchmark between pipeline releases and other analysis sources.The results obtained from the full-sized test can be viewed on the nf-core website.
Pipeline summary
- Read variants, proteins, or peptides and HLA alleles
- Generate peptides from variants or proteins or use peptides directly
- Predict HLA-binding peptides for the given set of HLA alleles
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.
First, prepare a samplesheet with your input data that looks as follows:
samplesheet.csv
:
Each row represents a sample with associated HLA alleles and input data (variants/peptides/proteins).
Now, you can run the pipeline using:
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.
