## 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.
