Thanks. I glance the whitepaper before. But it doesn't mention the bit
I
want.
In page 4 of the paper it says:
A note about .CEL Files
The Statistical Algorithms begin with information contained in the
.CEL
file generated by Microarray Suite software. The .CEL files contain a
captured image of the scanned GeneChip? array and calculations of the
raw intensities for probe sets. The me thod for calculating individual
cell intensities, thus generating the .CEL file, is not affected by
the
Statistical Algorithms. Therefore, it will not be discussed here.
I vaguely remember that the software discard the outermost pixels from
a
feature and use the 75% in the rest as the raw feature intensity. Is
it
correct? Is there any other thing being done on the raw data?
Regards,
Fai
