EXP_raw: Simulated Gene Expression

In SegCorr: Detecting Correlated Genomic Regions

Description

Gene expression profiles have been generated for 30 patients and 500 genes. Background correlation is set to 0.08 and the correlation for H1 regions to 0.5. The location of the H1 regions is as suggested in the work of Lai et al.(2005), i.e region 1 [101, 105], region 2 [201, 210], region 3 [301, 320] and region 4 [401, 440].

Usage

data("EXP_raw")

Format

Data frame containing the gene expression signal for 500 genes (rows) on 30 patients (columns).

#data(EXP_raw)
#G = cor(t(EXP_raw))## calculating the gene x gene correlation matrix
#image(G)## plotting the correlation matrix
