[BioC] affycomp problem

[Tarca Adi Laurentiu]

Hi everyone,
I am trying to use the read.dilution function of affycomp library, and I am 
getting the following error message:

"Error in "[.data.frame"(d, , rownames(pData(dilution.phenodata))) :
         undefined columns selected"

Looking at the code of the function I see that it is trying to select 
columns with names like: "94394hgu95v2a11" "94395hgu95v2a11" ...
while the data frame d has columns with names like   "94394hgu95a11" 
"94395hgu95a11"... .
I could perhaps solve the problem by inserting the missing "v2" in the 
column names of the .csv file but I wonder if
this is the right thing to do.
Is possible that the 75 slides data set that I received form Genelogic with 
.cel files names like
"94394hgu95a11" "94395hgu95a11"...  is not the one read.dilution was 
conceived to deal with?

Thanks for any suggestion,
Laurentiu
