Dear Marcus and Jean,
thanks for your help.

Jean, regarding your suggestions, I have tried them and this is what I 
get:

> maLayout(mydata.raw)<-mydata.layout
Error: Object "mydata.raw" not found
> maGnames(mydata.raw)<-mydata.names
Error: Object "mydata.raw" not found
> class(samples)
[1] "genericFunction"
> maTargets(mydata.raw)<-samples
Error: Object "mydata.raw" not found


Marcus, the six files are six different QuantArray files. They are tab 
delimited text files and the first part of the file (the first 12331 
rows) are information we don´t use. We use the second half of the file 
where the intensities for each channel are shown.
