[BioC] matchrpobes and HGU95A mismatch

[Saroj Mohapatra]

I would also like to know the source of this discrepancy.

Some probe sets on the array did not make it to the hgu95aprobe package 
(or, so it seems to me). And I could not figure out why these probe sets 
were left out (e.g., excessive cross-hybridization?) However, it is 
possible to explore these probe sets at Netaffx.

Hope some one with more knowledge would weigh in ...
