SAMTOOLS SORT

Sort bam file with samtools.

Software dependencies

  • samtools ==1.5

Example

This wrapper can be used in the following way:

rule samtools_sort:
    input:
        "mapped/{sample}.bam"
    output:
        "mapped/{sample}.sorted.bam"
    params:
        "-m 4G"
    threads: 8
    wrapper:
        "0.20.1/bio/samtools/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.
