Spotlight

Our widgets for functional genomics use Orange, a data mining and machine learning suite. Orange can be accessed through scripting in Python, or by visual programming in Orange Canvas.

In functional genomics, we have also designed a web-based tool for mutant data analysis called GenePath (also featured in Science's NetWatch).

Heat Map (2) widget

The combination of "Heat Map" and "Heat Map (2)" widgets provides for a magnifying glass. Genes selected in the "Heat Map" widget are displayed here at a finer granularity - each gene in its own row. We can change the parameters of visualization to get a detailed image with different information displayed.

The magnifying glass was not preprogrammed in the schema, but was programmed through an innovative combination of widgets.

In our analysis we inspect a gene whose expression has a clean-cut change between 6-8 hour. The gene was annotated to be a structural constituent of ribosome with is in concordance with the study (Van Driessche et al., 2002).
