Hi All:

I am trying to analyze C. elegans tiling array data using the
AffyTiling library. I use the bpmap file provided by Affymetrix.
The program reads CEL & bpmap files but exits with error message
after traformation (see out put below).
Can anybody explain how I should avoid this problem?
Any help would be appreciated.
