[BioC] Creating a CDFenv without cdf file

[Nicholas Lewin-Koh]

Hi,
I have many cel files from a custom chip, but I do not have the cdf
file. I do have the chip design information and
and the seqence information but they are in seperate text files. I
looked in the altcdfenvs package and it looks
as if I could hijack another env and change the parameters as needed.
Has anyone done this? Is there a tutorial
or Vignette I overlooked? Is there another tool for building cdf files?

thanks
Nicholas
