Hello. I am using "affy" to process HG_U95Av2 chip. I want to know
how
each spot (probe cell) is aligned on a chip. When I read in a data
using
(Data <- ReadAffy( )) and write out to a file, each spot is numbered
from 1 to
409600. How can I determine probe cells and their corresponding probe
pairs
and probe sets from this file? Is there a list that corresponds to
these spot
numbers? I also would like to find out which probe is aligned on which
probe
cell. Thank you.
