**What it does**

Clusters of read alignments (provided as bam files) are aggregated along regions of
*variable* lengths. The Clustering algorithm works as follows:

A read is clustered with the next 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
(default setting, only forward reads or reverse reads can be clustered, separately), or to
ignore this polarity.

Clusters of reads are plotted as single bars, their coordinates being the medians of
the flanking coordinates of the clusters.

In addition, cluster are reported in a bed file. There, 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).

Note that bed filtering options only affect the number of reported line in the bed file.
All clusters are shown in the plot. **i.e. the only parameter that affects the number of
found clusters is the clustering distance.**

**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, which can be arranged in a
data collection, are visualised side by side in a single pdf file and are reported in a
single bed file.
 
**Output**

A pdf file generated by the R package lattice, a dataframe used to plot the clusters, and
a bed file that reports significant clusters.
