Dear all,

I have a cancer dataset from GEO that labeled as having the platform GPL 91
(HG-U95A), and when I use justRMA() to read the data, I realize that the
GSMs are from HG_U95A and HG_U95Av2, and that gives me the error. I could
separately analyze the data but I just want to ask if anyone has experience
or comments about the difference between the two platforms AND could I seem
the data coming from one platform, and analyze them (eg. by using RMA); of
course if that's the case I have to "make" R believe that they are coming
from only one platform. Or what's the most proper way to analyze these kinds
of data ?

Greatly appreciate for the help and the comments

P.S.: this is a cancer dataset, with two types of disease state, and each
type could be either come from the HG-U95A or HG_U95Av2
