Some time ago I started working on some software which could be used in genomic data analysis. It was during my PhD studies at Warsaw University of Technology. I worked together with guys from Maria Sklodowska-Curie Memorial Cancer Centre and Institute of Oncology and recently we managed to publish the results in BMC Research Notes. It is about exploratory data analysis and visualisation in ChIP-Seq research (Chromatin immunoprecipitation coupled with next-generation sequencing). The article is available here, so you can freely read it. The application is called jChIP and is available to download from SourceForge project page. Feel free to read, use and test.
