quantilenorm - Quantile normalization over multiple arrays

Syntax

NormData = quantilenorm(Data)
NormData = quantilenorm(...,'MEDIAN', true)
NormData = quantilenorm(...,'DISPLAY', true)

Description

NormData = quantilenorm(Data), where the columns of Data correspond to separate chips, normalizes the distributions of the values in each column.

Note   If Data contains NaN values, then NormData will also contain NaN values at the corresponding positions.

NormData = quantilenorm(...,'MEDIAN', true) takes the median of the ranked values instead of the mean.

NormData = quantilenorm(...,'DISPLAY', true) plots the distributions of the columns and of the normalized data.

Examples

load yeastdata
normYeastValues = quantilenorm(yeastvalues,'display',1);
