Dear all,
I tried to post my question on aroma.affymetrix google group twice, but for some reason it was not there. 
I have to try to post  my question on bioconductor. Sorry about that.
I just start learning aroma.affymetrix package for Affy SNP6.0
analysis. I downloaded ugp,ufl,acs file from the link
http://www.aroma-project.org/chipTypes/GenomeWideSNP_6, followed the
example code, but I got the following warnings. I can't move to the
following steps. Would you please let me know what the problem is?
Thanks a lot,
Qian
