Error in getEAWP(object) : data object isn't of a recognized data class

Did you do this R error: unable to find an inherited method for function ‘exprs’ for signature ‘"list"’ ? Probably the same error, you are trying to fit that list into the function rather than the ExpressionSet.

Please use the formatting bar (especially the code option) to present your post better. You can use backticks for inline code (`text` becomes text), or select a chunk of text and use the highlighted button to format it as a code block. If your code has long lines with a single command, break those lines into multiple lines with proper escape sequences so they're easier to read and still run when copy-pasted. I've done it for you this time.

What is the output of class(DataSeries) and class(design) ?
