Dear list,

This is my first experience working on microarray data. I am trying to  
analyze Human Gene 1.0 ST microarray data with oneChannelGUI. However,  
this seems to be not a straightforward task. I have been playing  
around with data and the application and I am a little bit confused  
and without any result yet!

First, I installed all the packages and then, followed the user guide  
instructions.
When I select "GENE 1.0 ST ARRAYS: probe sets summary from Affymetrix  
APT" option to perform a new analysis, it asks me if I want to use APT  
for gene/exon summaries. I click "yes" and chose the organisms (in my  
case, Hs). Next, I select the working directory, the target file and  
answer "no" to the question "are you using genechips version 1.1?".  
Finally, as APT tool intensity summary option, I select "rma-sketch".  
Inmmediatly, I get a series of error messages (see below).

I really do not know what is happening here. I would like to make the  
background correction, normalization and summarization, and also run  
limma.
On the other hand, I can load a normalized tab delimited data set and  
apply some functions on it, but I do not know how to include the  
annotations into the final list of differential expressed genes (top  
table).
anybody has a suggestion about what is happening here and how could I  
solve it?
I would appreciate your help.

Best regards and thank you in advance for your attention.
Virginia.
