Dear Christian,
Just couldn't figure out what's wrong with my practice. I have 55
mouse
genome arrays. I tried both RMA and MAS5 for preprocession data. Both
methods returns only 21 readable lines. I checked the tmp_ files in
the
folder, which seemed much bigger than just 21 lines. Any hint?
Best,
Steve
