draw_score_histograms
=====================

``draw_score_histograms`` draws the histograms of the scores of the
resources of a GRR. It finds the GRR that starts at the current directory,
or at the ``-R`` repository. It writes the histogram files into the
directory of each score resource. The GRR must be a read-write GRR, for
example a local directory. Use it after you add or change a score resource,
so that the GRR info page of the resource shows the histograms.

Examples
--------

.. code-block:: bash

    draw_score_histograms

Draws the histograms of the score resource that contains the current
directory. If the current directory is not inside a resource, it draws the
histograms of every resource below the current directory. Run the command
from the GRR root to cover the whole repository.

.. code-block:: bash

    draw_score_histograms -R /data/grr -r hg38/scores/phyloP100way

Draws the histograms of one score resource of the GRR in ``/data/grr``.
The ``-r`` option takes a resource id or a glob pattern on resource ids, for
example ``hg38/scores/phyloP*``. The ``-R`` option sets the repository root
for the resource ids.
