How do we define FDR at the protein level in proteomics data?

WebThe spectra-cluster algorithm performs clustering in several rounds (see below). In each round, a lower target precision is being used. The precision is defined as the average cluster purity or rather the inverse of the proportion of incorrectly clustered spectra. A precision of 1 therefore means that only perfectly matching spectra are clustered.
