Hi,

I am trying to load data from .cel files from custom
affy chips, but I get the errors below.  The first
error was because I needed to load the cdf
environment.  So, I attempted to make the cdf
environment and got the second error.  The cdf file is
from resequencing data.  Is it possible to convert a
resequencing CDF file to a genotyping CDF file?  Or,
is there another function I can use to load a
resequencing CDF file?

Thanks,
Charlyn
