At first I would like to express the gratitude toward Oosting, J. and James
MacDonal for their help solving the previous problem I posted on this forum.
Now I have a new problem. I was trying to normalize set of microarray data
on HGU133 paltform. I put all the HGU133A platform chips in one directory
and all the other HGU133B chips on another directory. When I tried to
normalized them using same script HGU133A data worked fine but got error for
HGU133B platform data. The code is
library(affy)
Data <- ReadAffy()
eset <- mas5(Data)
Calls <-mas5calls(Data)
The errors I got are:
background correction: mas
PM/MM correction : mas
expression values: mas
background correcting...Warning message:
