... Thanks for your answer Petr. The only thing I'm concerned about is whether its acceptable to use ratios for example like I calculated by dividing with control and use those numbers directly to calculate p-values for example using something like limma?In this way the levels of proteins in each treatm ...

... Thanks a lot for your reply Shunyip. But I'm just wondering z-score is calculated as (x-mean)/sd. Here x then becomes log2FC values so i end up with 2 z-scores for each protein again ...

... Hi Devon, Thanks for your answer! You were right there was an error in my code somewhere. I fixed it so now the 2 values are not the same. About your comment on using Limma. I didn't exactly follow. You don't think using just a simple t-test and then adjusting for multiple comparisons is advisable? ...
