Dear all,

 

I'm a beginner in the preprocessing of microarray data. Currently, I'm facing the extraction of the expression data matrix from the raw data of an antibody microarray. I have GPR files from two different arrays before and after the washing, and a GAL file. How can I do that?

 

I have PANORAMA arrays (SIGMA), so anyone knows how can I do the normalization of the expression data?

 

Any ideas on these issues will be very welcome.

 

Regards,

 

Núria
