Orange Bioinformatics extends Orange, a data mining software package, with common functionality for bioinformatics. The provided functionality can be accessed as a Python library or through a visual programming interface (Orange Canvas). The latter is also suitable for non-programmers. Orange Bioinformatics provides access to publicly available data, like GEO data sets, GO and KEGG. All features can be combined with powerful visualization, network exploration and data mining techniques from the Orange data mining framework. WWW: https://github.com/biolab/orange3-bioinformatics
