Hi, I was wondering if anyone can suggest a MAGE-TAB tool to simplify the creation of IDF and SDRF files. I understand it's not hard to create those manually. But when one has multiple datasets, it's somewhat annoying to go to every IDF counting the number of fields each row has in order to be a proper tab- delimited file.
