The program requires Mathematica 7.01.0
The key function is Classify [datalist,options] where
datalist={data, genename, dataname}
data ={matrix for class 0, matrix for class 1}, matrix is gene expression by specimen genename a list of names of genes,
dataname ={name of data set, name of class0, name of class1}
To reproduce results in article, type ClassifyMS1[ ], ClassifyMS2[ ], ClassifyFig12[ ], ClassifySim1[ ], ClassifySim2[ ]
