I'm quite sure that 'StartPosition' and 'StopPosition' are *not* part of the Affymetrix CDF file format, that is, a CDF file cannot hold such extra information. In order words, even if you try to put it in a CDF file in text format as above, it will be ignored by an CDF file parsers, including the ones converting text CDFs into binary CDFs. /Henrik > > Thanks > > Rahul > > > > On Sep 15, 1:03 pm, rahul <v.rahul.sim...@gmail.com> wrote: >> Thanks a lot for the immediate reply.
