 Demo data can be downloaded here: [Demo Data](ModuleViewerDemoData).
 
+The regulator tree lets the user visualize regulators or other genes associated with the module above the main gene expression matrix.
+These "associated genes" can even be a complete other module, so *two modules can be compared to eachother*. To do this, make a copy of the original gene file, but replace the module ID of the modules to be compared, with the ID of the modules to be compared to. Then load this second file as a "regulator file". In a similar way, a new MVF file could be constructed, copying the original file, replacing the module IDs and changing the OBJECT key from GENES to REGULATORS.
