 title: "Detection of consensus regions inside a group of experiments"
-author: Astrid Deschenes, Fabien Claude Lamaze, Pascal Belleau and Arnaud Droit 
-abstract: The consensusSeekeR package is designed to detect consensus regions inside a group of experiments using genomic positions and genomic ranges.

+abstract: This package compares genomic positions and genomic ranges from
+    multiple experiments to extract common regions. The size of the analyzed 
+    region is adjustable as well as the number of experiences in which a 
+    feature must be present in a potential region to tag this region as a 
+    consensus region. In genomic analysis where feature identification 
+    generates a position value surrounded by a genomic range, such as ChIP-Seq 
+    peaks and nucleosome positions, the replication of an experiment may result 
+    in slight differences between predicted values. This package enables the 
+    conciliation of the results into consensus regions.
