**What it does**

Plots mapping statistics of read alignments along reference chromosomes or genes or arbitrary regions :

 - counts
 - mean sizes
 - median sizes
 - coverage depth
 - size distribution

Read counts, mean sizes and median sizes are computed by counting the number of 5' end of reads
in each position of a chromosome reference.
Coverage depths are computed from the input bam alignment files using the python pysam module.

The metrics mentioned above can be plotted either separately:

.. image:: one_plot.png

Or in all possible pairwise combinations:

.. image:: two_plot.png

For comparison purposes, values from bam alignment files can be normalized by a size factor
before plotting (Normalisation field)

*Cluster mode*

Cluster of read alignments are aggregated along regions of *variable* lengths. The Clustering
algorithm works as follows:

A read is clustered with the following read on the genomic reference if the two reads are
separated by at maximum the clustering distance (set in nucleotides). If clustered, the step is
repeated with the following read until clustering fails. A new cluster is then searched.

For clustering procedure, one has the possibility to consider the polarity of reads (only forward
reads or reverse reads can be clustered separately), or to ignore this polarity.

Cluster reads are plotted as for single reads, their coordinate being the median of extrem coordinates of the cluster.

In addition, cluster are reported in a bed file, where clusters can be filtered out upon various parameters,
cluster size, cluster read number or cluster read density (number of reads divided by the length of the cluster).

**Inputs**

bam alignment files that must be

  - single-read
  - sorted
  - mapped to the same reference

.. class:: warningmark

This tools follows a "map-reduce" procedure: multiple inputs, that can be arranged as a data collection,
are visualised side by side in a single pdf file.
 


**Output**

A pdf file generated by the R package lattice and one or two dataframes used to plot the data.
