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).
"GO Term Finder (2)" widget
is used to show the biological process annotation for all 800 genes in the input
set. The category "regulation of glycogen biosynthesis" is selected to
demonstrate that besides PIG1 (see the "Genome
Map" widget), PCL7 is another gene in the original dataset with
this GO biological_process annotation. The "Expression
Profiles (3)" widget is used to compare the expression profiles of these
two genes, and clearly these genes were not coexpressed in the experimental
conditions used. Comparison of the "Expression
Profiles" and "Expression
Profiles (3)" widgets graphs confirms that adjacent position, and not
the functional relatedness, is the reason for coexpression in the case of
CDC46 and PIG1 (see the "Genome Map"
widget).
