Hi,
I have a bunch of Affymetrix *.chp files in binary format. I do not
have
access to Affymetrix software for working with this and I want to do
subsequent analysis of this data with my own scripts anyway.
Can I use Bioconductor to convert such binary *.chp files into
human-readable cleartext (f.e. tab-delimited table)? Or otherwise
parse
them?
My goal would be a file with genes (not probes) and their expression
values.
As I understand it, normalization, summarization etc has already been
done
and is somewhere in the *.chp files, but I don't see a way to get the
data.
I figured out that Bioconductor let's me work with *.cel files using
the
affy package, but what about *.chp?!
Thanks.
Anton
