[BioC] is my normalization right?

Thank you for your answer!

My raw-data was from GenePix. Because I used only Cy3 in my whole
microarray experiment, I only extract data by the software,and try to
normalize the data by Bioconductor. 

I made a .txt file for the raw data, it was just like this:

Gene Name  Contrl(intensity)   Treat1(intensity)   Treat2(intensity) Treat3(intensity) 
1             
2
3
4
5
...

I want to use mutiple slides normalization with intensity dependent, is
it appropriate? And could you tell me howto? I am trying to find out
ways by reading Bioconductor's document and help files,but I feel really
difficult.

Thank you very much!
