pairs of probes from each probe set of Arabidopsis genechip (i.e

through the archive, I found that I can create a new cdf environment
that excludes the pairs that I'm not interested in. However, when I
tried using makecdfenv to create the new CDF package, I get a
Segmentation fault. I'm using R Version 1.9.0 (2004-04-12) on UNIX
platform.

have a ATH1-121501.CDF of type Channel Definition File (which I didn't
have problem reading) and I modified this file by deleting 1 pair of
probes from 266455_at. I saved it as another .CDF. I opened the file
using EditPadLite Version 5.3.0 and did the modification from there as
well. I'm not very sure where did I make mistake(s). I'd appreciate
any comment on this.
