exprprofrange - Calculate range of gene expression profiles

Syntax

Arguments

Data	DataMatrix object or numeric matrix of expression values, where each row corresponds to a gene.
ShowHistValue	Controls the display of a histogram with range data. Default is: false — When output values are specified. true — When output values are not specified.

Description

Range = exprprofrange(Data) calculates the range of each expression profile in Data, a DataMatrix object or numeric matrix of expression values, where each row corresponds to a gene.

[Range, LogRange] = exprprofrange(Data) returns the log range, that is, log(max(prof))- log(min(prof)), of each expression profile. If you do not specify output arguments, exprprofrange displays a histogram bar plot of the range.

... = exprprofrange(Data, 'ShowHist', ShowHistValue) controls the display of a histogram with range data. Choices for ShowHistValue are true or false.

Examples

1. Load the MAT-file, provided with the Bioinformatics Toolbox software, that contains yeast data. This MAT-file includes three variables: yeastvalues, a matrix of gene expression data, genes, a cell array of GenBank accession numbers for labeling the rows in yeastvalues, and times, a vector of time values for labeling the columns in yeastvalues

   load yeastdata

2. Calculate the range of expression profiles for yeast data as gene expression changes during the metabolic shift from fermentation to respiration. Display a histogram of the data.

   range = exprprofrange(yeastvalues,'ShowHist',true);
