Hi Luis,

Thank you very much. I'm already testing it and for a few datasets that I 
have tested it looks good and quite comparable to the Xpress based on 
areas, although with much narrow standard deviation. Is it planned to use 
this as an alternative for the Xpress quantitaion alos at the protein 
level? Right now I'm exploring if I could get an intensity based ratio at 
the protein level by using the peptide information (if it contribute with 
evidence for the protein assembly) and then calculating the mean of the 
peptide ratios of every protein.

Cheers,

Alejandro
