j.nome.s is a fast, simple, lightweight genome browser. It is built on top of expressjs and Node.JS, and uses MongoDB for storing the data.

Current genome browsers include GBrowse, the UCSC genome browser or Jbrowse. The main problem with those project, is that they heavily rely on perl and BioPerl scripts in order to both crunch data and render the output. Although perl is widely used by bioinformaticians, it is a very inelegant language, very often leading to bloatware. Representing genomes is not an easy task considering the huge amout of data that has to be handled and shown in an intelligible way.

j.nome.s aims to provide a simple genome browser environment, convenient to both the user, and the developer. It is based on Node.JS, which allowed to build a custom non IO-blocking server application. The data is stored in a MongoDB database, providing a scallable and efficient way to respectively store and access huge amount of data.

j.nome.s is an ongoing project initiated by Alexis GRIMALDI and supervised by Avetis KAZARIAN.
