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

Generate a joint id space across each graph and merge them all.


Example
-------

This wrapper can be used in the following way:

.. code-block:: python

    rule merge:
        input:
            vgs=["c.vg", "x.vg"]
        output:
            merged="graph/wg.vg"
        log:
            "logs/vg/merge/wg.log"
        wrapper:
            "v3.0.1/bio/vg/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.
