Dear All, 

I am analyzing Cromer A, Carles A et al. hypopharyngeal cancer data at various stages of progression. In their Oncogene paper (2004 Apr 1;23(14):2484-98), they mentioned  they used hgu95a chip.When I loaded the all .cel files into R 2.1.0(OS:windows XP), I was told that:
library(affy) 
Data <- ReadAffy() 
Error in initialize(value, ...) : Cel file D:/GSE2379_CEL/GSM44799.CEL does not seem to be of HG_U95Av2 type.

Overall, 18 .cel files like GSM44799 do not seem to be of HG_U95Av2 type.

Why happened so? I should go back to low version R like R1.9.0? What difference between HG_U95A and HG_U95Av2 type?

How to fix it? 

please help me and thank you.

 



Best Regards
