Dear all, 

Let me ask you a question.

I have been analyzing a two-color microarray data but I do not have the .gal file. I tried to get this file from Agilent web site but I do not have the following information: Design ID and slide format. So, is there another possibility to get this information? Is there another way to get the gene list?

 

Thanks in advance.

Have a nice day

GAL files are only for GenePix. You won't have or need a GAL file when analyzing Agilent arrays -- all the relevant information should be in the Agilent files.

As far as I can see from the code that you've posted elsewhere on this site, the gene information should already have been read for you automatically by read.maimages(). You should see this information in the output from topTable(). Why do you say you don't have a gene list?

Dear Gordon, 

You are right. I apologize for my lack of experience. 

I have the following information: 

. Spot ID  and GenBank Accession Number. How can I replace the GenBank Accession Number by Gene Name?

Thanks in advance
