Dear all,
 
I have MEV files and I am using limma. I created the RGlist. However
 
1. there are spots with intensity zero which makes the log ratio to infinity. How to remove them?
2. There are empty (blank) genes and negative control genes in the RG list. I create a spotfile.txt to identify them but I would like to remove then as well.
 
Thanks
 
Yolande
