Hi Anbarasu.
To extract just the raw probe intensities (before BG adjustment or
normalization), how about something like:
cdf <- AffymetrixCdfFile$byChipType(chipType, tags="coreR3,A20071112,EP")
cs <- AffymetrixCelSet$byName("tissues", cdf=cdf)
u <- 1:nbrOfUnits(cdf)
u <- 1:10 # could use li
Hi All,
I have been looking at extracting raw data for core transcripts from
HuEx-1_0-st-v2 chip type. I have downloaded the custom CDF file provided in
http://www.aroma-project.org/node/122.
chipType <- "HuEx-1_0-st-v2"
cdf <- AffymetrixCdfFile$byChipType(chipType, tags="core")
print(cdf)
Affyme
