We only provide cdf and probe packages for commercially available Affy 
chips, specifically excluding custom chips. There are two reasons for this:

1.) A custom chip implies that the chip was produced specifically for 
one (or a very small group of) researcher(s). Because these chips won't 
be widely distributed, it doesn't make sense to spend the time and 
effort to maintain these packages.

2.) The cdf and probe packages for custom chips are not freely 
downloadable from Affy's website. We re-build the cdf and probe packages 
for every release, so we have to be able to easily get the original 
source data. In addition, there may be legal issues concerning the 
ownership of the custom chip cdf and probe data that we don't want to 
get involved with.

But thanks for the offer!

Best,

Jim
