\title{Glioblastoma Multiforme (GBM) Data by Verhaak et al. (2010)}
\description{
 Microarray data from Glioblastoma multiforme (GBM) downloaded from
 the TCGA website (\url{http://cancergenome.nih.gov}). The data
 is provided as an \code{ExpressionSet} object containing RMA-processed
 expression values.
}
\usage{data(gbm_VerhaakEtAl)}
\details{
    The data is contained in an \code{ExpressionSet} object called
    \code{gbm_eset} and was obtained using RMA (Irizarry et al. 2003).
