SAMTOOLS MERGE
==============


.. image:: https://img.shields.io/github/issues-pr/snakemake/snakemake-wrappers/bio/samtools/merge?label=version%20update%20pull%20requests
   :target: https://github.com/snakemake/snakemake-wrappers/pulls?q=is%3Apr+is%3Aopen+label%3Abio/samtools/merge

Merge two bam files with samtools.


Example
-------

This wrapper can be used in the following way:

.. code-block:: python

    rule samtools_merge:
        input:
            ["mapped/A.bam", "mapped/B.bam"],
        output:
            "merged.bam",
        log:
            "merged.log",
        params:
            extra="",  # optional additional parameters as string
        threads: 8
        wrapper:
            "v3.0.1/bio/samtools/merge"

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

When running with

.. code-block:: bash

    snakemake --use-conda

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


Notes
-----

* The `extra` param allows for additional program arguments (not `-@/--threads`, `--write-index`, `-o` or `-O/--output-fmt`).
