Adjusting expression variance for zero-centered normalisation

Description

This function adjusts the variance of the gene expression according to the zero-centered normalisation.

Usage

clusterNormVar(x)

Arguments

x a vector which contains the variance of gene expression level on log2 scale.

Details

Vector x is related to a gene and each element is related to a chip.

Value

The return vector is in the same format as the input x.
