dirHub: a trackHub configurator with directory structure projection

SummaryTrack Data Hub is a mechanism enabling us to visualize genomics data as tracks along genome coordinates and share them over the Internet, relying on a web server hosting data files and genome browsers offering graphical representations. It requires an accessible configuration file specifying all graphical parameters and track hierarchy, in addition to the data files. Here dirHub is developed to assist generation of the configuration file by projection of a file directory structure, which makes it possible to set up trackHub visualization mostly by file operations.\n\nAvailability and implementationIt is implemented in ruby and the source code is available at https://github.com/hkawaji/dirHub/. It is tested on the UCSC Genome Browser and the Hub Track Database Definition (v2).
