**What it does**

This tool produces a table ranking the pathways based on the percentage
of genes in an input dataset, out of the total in each pathway.
Alternatively, the tool ranks the pathways based on the change in
length and number of paths connecting sources and sinks.  This change is
calculated between graphs representing pathways with and without excluding
the nodes that represent the genes in an input list.  Sources are all
the nodes representing the initial reactants/products in the pathway.
Sinks are all the nodes representing the final reactants/products in
the pathway.

If pathways are ranked by percentage of genes affected, the output is
a tabular dataset with the following columns:

   1. number of genes in the pathway present in the input dataset
   2. percentage of the total genes in the pathway included in the input dataset
   3. rank of the frequency (from high freq to low freq)
   4. name of the pathway

If pathways are ranked by change in length and number of paths, the
output is a tabular dataset with the following columns:

   1. change in the mean length of paths between sources and sinks
   2. mean length of paths between sources and sinks in the pathway including the genes in the input dataset.  If the pathway do not have sources/sinks, the length is assumed to be infinite (I)
   3. mean length of paths between sources and sinks in the pathway excluding the genes in the input dataset.  If the pathway do not have sources/sinks, the length is assumed to be infinite (I)
   4. rank of the change in the mean length of paths between sources and sinks (from high change to low change)
   5. change in the number of paths between sources and sinks
   6. number of paths between sources and sinks in the pathway including the genes in the input dataset.  If the pathway do not have sources/sinks, it is assumed to be a circuit (C)
   7. number of paths between sources and sinks in the pathway excluding the genes in the input dataset.  If the pathway do not have sources/sinks, it is assumed to be a circuit (C)
   8. rank of the change in the number of paths between sources and sinks (from high change to low change)
   9. name of the pathway
