Updates local systems biology databases, like gene ontologies, annotations, gene names, protein interaction networks, and similar.
Many widgets in Orange bioinformatics add-on rely on information on genes, gene sets, pathways, and alike. This information is stored on your local computer when the widget requires them for the first time. The corresponding data comes from different web resources, and is either preprocessed and then stored on Orange server, or accessed directly from a dedicated web site.
Orange does not change the data on your local computer, and with time this becomes different to the newest version of the online data sets. Databases widget can update the data on your local machine, and can also be used to manage (remove or add) any locally stored systems biology data set.
To get a more detailed information on the particular database that requires an update, hover on its :obj:`Update` button.
