What it does
--------------

``plotHeatmap`` visualizes scores associated with genomic regions, for example ChIP enrichment values around the TSS of genes.
Like ``plotProfile``, it requires that computeMatrix was run first to calculate the values.

We have implemented a number of optional parameters to optimize the visual output and we encourage you to play around with the min/max values
displayed in the heatmap as well as with the different coloring options.

**TIP:** *If your data is rather sparse and the resulting heatmap is too black, change the "Missing data color" to white (via "Advanced options").*

The most powerful option is probably the **k-means/hierarchical clustering** where you can sort your regions into groups of regions with similar score distributions.

**NOTE:** *The clustering will only work if you supplied a single BED file to computeMatrix. plotHeatmap cannot cluster regions within pre-defined groups. Moreover, k-means will be much faster than hierarchical clustering.*

Output
--------------

This is a heatmap based on two bigWig files generated with default settings and k-means clustering.

.. image:: $PATH_TO_IMAGES/plotHeatmap_example.png
   :width: 600
   :height: 694

.. image:: $PATH_TO_IMAGES/plotHeatmap_example02.png
    :width: 600
    :height: 694

In addition to the image, ``plotHeatmap`` can also generate the values underlying both the heatmap.

See the following table for the optional output options:

+-----------------------------------+--------------------+-----------------+-----------------+
|  **optional output type**         |  **computeMatrix** | **plotHeatmap** | **plotProfile** |
+-----------------------------------+--------------------+-----------------+-----------------+
| values underlying the heatmap     |  yes               | yes             | no              |
+-----------------------------------+--------------------+-----------------+-----------------+
| values underlying the profile     | no                 | no              | yes             |
+-----------------------------------+--------------------+-----------------+-----------------+
| sorted and/or filtered regions    | yes                | yes             | yes             |
+-----------------------------------+--------------------+-----------------+-----------------+
