I'm using ChAMP to run methylation profiling of tumors and adjacent normal patient's sample. I've played around using the lung test data and successfully derived DMP and DMR results. But I'm having issues loading champ data for my actual data. The CSV file that I'm using has just the same format as the one with the lung test data (trial dataset given by ChAMP).

This is the error that occured;

Error in champ.import(directory, arraytype = arraytype) :     Error Match between pd file and Green Channel IDAT file.
