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

This tool computes the average scores for every genomic region for every bigWig file that is provided. In principle, it does the same as ``multiBamSummary``, but for bigWig files.

The analysis is performed for the entire genome by running the program in 'bins' mode, or for certain user selected regions (e.g., genes) in 'BED-file' mode.

Typically the output of ``multiBigwigSummary`` is used by other tools, such as ``plotCorrelation`` or ``plotPCA``, for visualization and diagnostic purposes.


Output
--------

The default output is a **compressed file** that can only be used with ``plotPCA`` or ``plotCorrelation``.

To analyze the average scores yourself, you can get the **uncompressed score matrix** where every row corresponds to a genomic region (or bin) and each column corresponds to a sample (BAM file). (To obtain this output file, select "Save raw counts (coverages) to file" )
