I have to analyse some data from MG_U74 chips that contain 2613 bad
probesets (antisense DNA strand) resulted from a mistake of
Affymetrix.
I need to remove these bad probeset from CEL file before I regenerate
data
(from CEL files ) because some algorithms e.g. RMA, may use these bad
probesets to do normalization. I called Affymetrix but was told
that
their mask files can remove bad probesets only after data is regerated
from
CEL files.
For anybody who has experience in such a thing or has knowledge on how
to
resolve this issue, please give some suggestions.
