There are 489 samples measured on 321 genes. Sample IDs are in the row names
and gene names are in the column names. This data set is used for clustering
HGSC into subtypes with prognostic significance. The cluster assignments
obtained by TCGA are indicated by the last six characters of each row name in
hgsc: MES.C1, IMM.C2, DIF.C4, and PRO.C5
