My name is Oksana Korobko and I'm Postdoc at LACDR, Leiden University, the
Netherlands. 

I do the statistical analysis of microarray data for Affymetrix Rat Gene 1.1
ST Array Plate. For normalization I need cdf, probe and df files. I cannot
find the cdf and probe files for this type of array. There are only cdf
(ragene10stv1cdf
<http://www.bioconductor.org/help/bioc-views/release/data/annotation/html/ra
gene10stv1cdf.html> ) and probe (ragene10stv1probe
<http://www.bioconductor.org/help/bioc-views/release/data/annotation/html/ra
gene10stv1probe.html> ) files for Affymetrix  Rat Gene 1.0 ST, but there are
db.file for Affymetrix Rat Gene 1.1 ST (ragene11stprobeset.db
<http://www.bioconductor.org/help/bioc-views/release/data/annotation/html/ra
gene11stprobeset.db.html> ) and for Affymetrix Rat Gene 1.0 ST
(ragene10stprobeset.db
<http://www.bioconductor.org/help/bioc-views/release/data/annotation/html/ra
gene10stprobeset.db.html> ).

My question is: Can I use cdf and probe files from previous version 1.0 ST
to my Rat Gene 1.1 ST data? And if the previouse answer is posistive, what
db.file should I use for 1.1 ST array ragene11stprobeset.db
<http://www.bioconductor.org/help/bioc-views/release/data/annotation/html/ra
gene11stprobeset.db.html>  or ragene10stv1probe
<http://www.bioconductor.org/help/bioc-views/release/data/annotation/html/ra
gene10stv1probe.html> ?

 

Many thanks in advance,

Oksana Korobko
