Write expression values in ExpressionSet object to text file
Syntax
exprWrite(ESObj, File)
exprWrite(..., 'Delimiter', DelimiterValue,
...)
exprWrite(..., 'Precision', PrecisionValue,
...)
exprWrite(..., 'Header', HeaderValue,
...)
exprWrite(..., 'Annotated', AnnotatedValue,
...)
exprWrite(..., 'Append', AppendValue,
...)
Description
exprWrite( writes
the expression values in the ESObj, File)Expressions element
(DataMatrix object) from an ExpressionSet object to a text file, using
the delimiter \t to separate columns. exprWrite writes
the data starting at the first column of the first row in the destination
file.
exprWrite(..., ' calls PropertyName', PropertyValue,
...)exprWrite with optional properties
that use property name/property value pairs. You can specify one or
more properties in any order. Enclose each PropertyName in
single quotation marks. Each PropertyName is
case insensitive. These property name/property value pairs are as
follows:
exprWrite(..., 'Delimiter', specifies a delimiter symbol to use as a column separator.
Default is DelimiterValue,
...)'\t'.
exprWrite(..., 'Precision', specifies the precision for writing the data to the
text file. Default is PrecisionValue,
...)5.
exprWrite(..., 'Header', specifies the first line of the text file. Default
is the HeaderValue,
...)Name property for the DataMatrix object.
exprWrite(..., 'Annotated', controls the writing of row and column names to the
text file. Choices are AnnotatedValue,
...)true (default) or false.
exprWrite(..., 'Append', controls the appending of the expression values to AppendValue,
...)File when
it is an existing file. Choices are true or false (default).
If false, exprWrite overwrites File.

Examples
Construct an ExpressionSet object, ESObj,
as described in the Examples section
of the bioma.ExpressionSet class reference page.
Write the expression values in the ExpressionSet object to a text
file:
% Write expression values to text file exprWrite(ESObj, 'myexpressiondata.txt')
