https://img.shields.io/github/issues-pr/snakemake/snakemake-wrappers/bio/bedtools/sort?label=version%20update%20pull%20requests

Sorts bed, vcf or gff files by chromosome and other criteria.

Example

This wrapper can be used in the following way:

rule bedtools_sort:
    input:
        in_file="a.bed"
    output:
        "results/bed-sorted/a.sorted.bed"
    params:
        ## Add optional parameters for sorting order
        extra="-sizeA"
    log:
        "logs/a.sorted.bed.log"
    wrapper:
        "v1.25.0-52-g79342b73/bio/bedtools/sort"

rule bedtools_sort_bed:
    input:
        in_file="a.bed",
        # an optional sort file can be set as genomefile by the variable genome or
        # as fasta index file by the variable faidx
        genome="dummy.genome"
    output:
        "results/bed-sorted/a.sorted_by_file.bed"
    params:
        ## Add optional parameters
        extra=""
    log:
        "logs/a.sorted.bed.log"
    wrapper:
        "v1.25.0-52-g79342b73/bio/bedtools/sort"

rule bedtools_sort_vcf:
    input:
        in_file="a.vcf",
        # an optional sort file can be set either as genomefile by the variable genome or
        # as fasta index file by the variable faidx
        faidx="genome.fasta.fai"
    output:
        "results/vcf-sorted/a.sorted_by_file.vcf"
    params:
        ## Add optional parameters
        extra=""
    log:
        "logs/a.sorted.vcf.log"
    wrapper:
        "v1.25.0-52-g79342b73/bio/bedtools/sort"

Note that input, output and log file paths can be chosen freely.

When running with

snakemake --use-conda

the software dependencies will be automatically deployed into an isolated environment before execution.

Software dependencies

  • bedtools=2.30.0

Input/Output

Input:

  • BED/GFF/VCF files
  • optional a tab separating file that determines the sorting order and contains the chromosome names in the first column
  • optional a fasta index file

Output:

  • sorted BED/GFF/VCF file
