   :target: https://github.com/snakemake/snakemake-wrappers/pulls?q=is%3Apr+is%3Aopen+label%3Abio/gatk/collectalleliccounts

Collects reference and alternate allele counts at specified sites.


**URL**: https://gatk.broadinstitute.org/hc/en-us/articles/13832754187035-CollectAllelicCounts

Example
-------

This wrapper can be used in the following way:

.. code-block:: python

    rule collectalleliccounts:
        input:
            bam=["mapped/a.bam"],
            intervals=["a.interval_list"],
            ref="ref/genome.fasta"
        output:
            counts="a.counts.tsv",
        log:
            "logs/gatk/collectalleliccounts.log",
        params:
            extra="",  # optional
            java_opts="",  # optional
        resources:
            mem_mb=1024,
        wrapper:
            "v3.0.1/bio/gatk/collectalleliccounts"

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.


Software dependencies
---------------------

* ``gatk4=4.4.0.0``
* ``snakemake-wrapper-utils=0.6.2``

Input/Output
------------
**Input:**

* ``bam``: BAM/SAM/CRAM file containing reads
* ``intervals``: one or more genomic intervals over which to operate
* ``ref``: reference FASTA file

**Output:**

* ``counts``: tab-separated values (TSV) file with allelic counts and a SAM-style header



Params
------

* ``java_opts``: additional arguments to be passed to the java compiler, e.g. "-XX:ParallelGCThreads=10" (not for `-XmX` or `-Djava.io.tmpdir`, since they are handled automatically).

* ``extra``: additional program arguments.
