From: Improved results in proteomics by use of local and peptide-class specific false discovery rates
Measurement | Formula | Description |
---|---|---|
Corroborating (c) hits | Â | Correct assignments matching together with others to a protein |
Non-corroborating (nc) hits | Â | Correct assignments matching singly to a protein |
FDR (global FDR) |
estimated by
| Fraction of incorrect assignments above the score threshold |
Local FDR | FDR for peptides with score (S):
| Fraction of incorrect assignments within a score window |
CNC Local FDR | Â | Fraction of incorrect assignments within a score window, separately for assignments matching together with others (c) or singly (nc) to a protein |
