Dear Cheng,

I know you are very busy and I am sorry to bother you.

I am analyzing a set of HSC gene microarray. dChip crashes every time
when I try to normalize the data without giving error messages. I
wonder if the gene file and annotation file that I am using are not
compatible. From our collaborator, i.e., the owner of the CEL files,
the platform that he used is Affy HTA System in 96-well platform. I am
using HT_HG-U133A.cdf and HT_HG-U133A.na29.annot.csv from Affymetrix
library. Are these the files to use? What other reasons may crash
dChip?

Also, the summary file shows all the p call% are zero. Is this normal
or I did something wrong?

Thank you very much.
Wendy
