Log2 transformed data is normalized using the function "justvsn" from the VSN package.

The VSN (Variance Stabilizing Normalization) attempts to transform the data in such a way that the variance remains nearly constant over the intensity spectrum

Usage

performVSNNormalization(rawMatrix)

Arguments

rawMatrix

Target matrix to be normalized

Value

Normalized matrix

Examples

data(example_data_only_values_small)
normMatrix <- performVSNNormalization(example_data_only_values)
