Hi, I want compare affy signal expression and rma, which are supposed to be somewhat hightly related or identical. But when I plot the normalized log2(affy) vs rma.There is a certain shape in all chips instead of being a ling. What might be the reasons? Thanks!

the reason is that they are different. for more details, see http://nar.oupjournals.org/cgi/content/full/31/4/e15?ijkey=EAz2cYYbEWQ rE&keytype=ref&siteid=nar On Mon, 30 Jun 2003, Jingqin luo wrote: > Hi, > I want compare affy signal expression and rma, which > are supposed to be somewhat hightly related or > identical.
