Process given file with tabix (e.g., create index).

URL: https://www.htslib.org/doc/tabix.html#INDEXING_OPTIONS

Example

This wrapper can be used in the following way:

rule tabix:
    input:
        "{prefix}.vcf.gz",
    output:
        "{prefix}.vcf.gz.tbi",
    log:
        "logs/tabix/{prefix}.log",
    params:
        # pass arguments to tabix (e.g. index a vcf)
        "-p vcf",
    wrapper:
        "v4.6.0-24-g250dd3e/bio/tabix/index"

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.
