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

When reporting problems on aroma.affymetrix, make sure 1) to run the latest
version of the package, 2) to report the output of sessionInfo() and
traceback(), and 3) to post a complete code example.
