**What it does**

BEC integrates the results of expression analysis and ChIP-chip analysis. For each transcript the number of peaks matching in the promoter and/or within the gene body is calculated.

PLEASE, for more detailed information refer to the CARPET user Manual:
click to download_ it.

-----

**Parameters:**

- **Analysis type:** 
                     - **promoter:** only the peaks matching in the promoter region (defined by user) are associated with the transcript
                     - **all gene:** peaks matching in the promoter and within the gene body are associated with the transcript
- **result output:** 
	- **# of matches:** the number of matching peaks are reported
	- **max value:** the highest score among all matching peaks is reported
                     
--------

.. class:: warningmark

If a peak matches with more than one transcript, it is associated with both.

**INPUT FILES**

- Expression file: file created by TEA
- ChIP on chip GFF results: file create by PeakPicker (or any GFF file)

**OUTPUT FILES**

.. image:: static/images/CARPET/bec_output.png

.. class:: infomark

This results table can be used again as input expression file, to add another ChIP-chip experiment.
