This procedure is used to compute ratios of peptide and protein abundances and then to perform a statistical analysis. The significance of ratios varations is then computed at protein and protein levels using two statistical tests (T-Test and Z-Test). Several filters can also be set to increase the quality of quantitative results.
Here is the description of the parameters that could be modified by the user.
Peptide abundances can be summarized into protein abundances using several mathematical methods:
