Description
If the assay.filename uses the microarray technology, it retrieves an object of the class MIAME with the minimum information about the experiment. Otherwise, it outputs a message indicating that the method is not valid for assays not using the microarray technology.
Usage
1
getMIAMEMetadata(isa, assay.filename)
Arguments
isa
An object of the ISAtab-class.
assay.filename
A string indicating the name of an assay file. It must correspond to a microarray-based assay for the function to return a valid value.
Value
It retrieves an object from the MIAME class or an error message.
