**What it does**

Run RnaChipIntegrator to analyse ChIP data against a set of list of "canonical
genes" for a specific organism/genome build, identifying the nearest ChIP peaks
to each cannonical gene (vice versa).

For ChIP peaks defined as regions the following analyses are performed:

 * **TranscriptsToPeakEdges**: reports the nearest transcripts with the smallest
   distance from either their TSS or TES to the nearest peak edge.

 * **TSSToPeakEdges**: reports the nearest transcripts with the smallest distance
   from their TSS to the nearest peak edge.

For ChIP peaks defined as summits:

 * **TSSToSummits**: reports the nearest transcripts with the smallest distance
   from the TSS to the nearest peak summit.

 * **PeaksToTranscripts**: reports the nearest peak summits with the smallest
   distance to either the TSS or TES of each transcript.

RnaChipIntgerator can be obtained from

.. class:: infomark

**Input**

The ChIP-seq data must be in a tab-delimited file with 3 columns of data for each
ChIP peak (one per line):

====== ========== ======================================================================
Column Name       Description
====== ========== ======================================================================
     1 chr        Chromosome name (must match one of those in expression data file)
     2 start      Start position of the peak 
     3 end        End position of the peak (start + 1 for summit data)
====== ========== ======================================================================

The ChIP peak data can be either the summit (in which case 'end' - 'start' = 1) or the
entire extent of the binding region (with 'start' and 'end' indicating the limits).

.. class:: infomark

**Output**

The outputs from this tool vary depending on the type of ChIP data that is input (i.e
summits or peaks), however generally there is one tab-delimited results file for each
analysis described above in the **What it does** section (some analyses output a second
file with just the "best" hits).

A history item will be generated for each output file, unless the option to put them
into a single zip archive is selected; this archive file will have to be downloaded
and unzipped on your local machine. It is recommended that you refer to the
RnaChipIntegrator documentation for information on the contents of each output file:
https://github.com/fls-bioinformatics-core/RnaChipIntegrator/blob/master/doc/MANUAL.markdown

In addition an Excel spreadsheet (with one page for each analysis performed) is always
produced.
