Thank you very much! I have figured out this problem.

Hi Yaping,
The cdf file should not be in the working directory, but in a
chip-type-specific subdirectory of the 'annotationData' directory, as
explained in the page Setup: Location of annotation data files:
http://aroma-project.org/node/66
Please see this page for further info. In your example, the cdf file
should be in
annotationData/chipTypes/Mapping250K_Nsp
Best,
Pierre

hi,
I just installed aroma.affymetrix in my mac computer (Mac OS X 10.6.7).
The
R version is 2.13.1.
I want to read this cdf file Mapping250K_Nsp.cdf:
cdf - AffymetrixCdfFile$byChipType(Mapping250K_Nsp)
Error in list(`AffymetrixCdfFile$byChipType(Mapping250K_Nsp)` =
environment, :
[2011-08-04 16:01:17] Exception: Could not locate a file for this chip
type:
Mapping250K_Nsp
at throw(Exception(...))
at throw.default(Could not locate a file for this chip type: ,
paste(c(chipType, tags), collapse = ,))
at throw(Could not locate a file for this chip type: ,
paste(c(chipType,
tags), collapse = ,))
at method(static, ...)
at AffymetrixCdfFile$byChipType(Mapping250K_Nsp)
The cdf file is in the current directory. Can anybody tell me how to fix
it!
Thanks,
Yaping
