The top former specified categories will be printed on screen while only 30 categories will be displayed for 'ALL'. All categories can be saved in a specified file. topGenes is similar to top, but only top 5 genes will be displayed for 'ALL'. genesOrderBy could be an integer to specify column to be sorted.
