nf-core/variantbenchmarking

Edit

Introduction

nf-core/variantbenchmarking is a bioinformatics pipeline that …

1. Standardization of SVs in test VCF files
2. Normalization of SVs in test VCF files
3. Normalization of SVs in truth VCF files
4. SV stats and histograms
5. Germline benchmarking of SVs
6. Somatic benchmarking of SVs
7. Final report and comparisons

Usage

Supported SV callers: Manta, SVaba, Dragen, Delly, Lumpy .. Available Truth samples: HG002, SEQC2

• If you have unresolved SVs, it is recommended to use only truvari with —pctsim 0.

• The size filtration parameters provided by truvari and svbenchmark do not apply in the same way. That is why using them is not recommended through the pipeline, but variants can be filtered safely in vcf normalization steps.

• Please note that it is not possible to use exactly the same parameters for different benchmarking methods.

Now, you can run the pipeline using:

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

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.
