Hello,

Can you help me to manage the following error message in trying to import GPL570 and convert it to csv file in order to work in excel?

Thank you,

There is no need to bother using R if you just want to get the annotation data in an Excel spreadsheet. Just go to the webpage for GPL570, and either download the table from that page, or click the link for the Affy website to get the updated na35 version.

Thank you James, 

I need the expression values of all the samples in that platform for comparative analysis using Excel
