Summary: Aggregation plots are frequently used to evaluate signal distributions at user-interested points in ChIP-Seq data analysis. agplus, a new and simple command-line tool, enables rapid and flexible generation of text tables tailored for aggregation plots from which users can easily design multiple groups based on user-definitions such as regulatory regions or transcription initiation sites.

Availability and Implementation: This software is implemented in Ruby, supported on Linux and Mac OSX, and freely available at http://github.com/kazumits/agplus
