Dear All,
I have 20 chips, and I used R to standardize the CEL files.Then, i got an expression value data of all chips.And I also downloaded the annotation csv format from NetAffy.(HG-U133_Plus_2 Annotations, CSV format, Release 30 (22 MB, 11/15/09))
Here's my code. 
########test = justRMA()eset.st = standardise(test)
exprs.st = exprs(eset.st)e.out = exprs.stdim(e.out) #* 54675 20########
However, i found out that the order of the rownames(e.out) is a little different to the row name of hgu133plus2.csv. The order from 54630 to 54640 is not the same to these two rows. 
They should be the same,right? Is "hgu133plus2cdf" the problem? How could I solve it?
Thanks!!!!! 
Best,Gina
