exprprofrange - Calculate range of gene expression profiles
Syntax
Range = exprprofrange(Data)
[Range, LogRange] = exprprofrange(Data)
... = exprprofrange(Data,
'ShowHist', ShowHistValue)
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. Choices
are true or false (default). |
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 (default).
Examples
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
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);
