Score distribution

Peptide score distribution

Peptide score distribution. Ions score is −10log(P), where P is the probability that the observed match is a random event. Individual ions scores > 17 indicate identity or extensive homology (p<0.05).

Protein score distribution for the first 50 proteins

[Deprecated] Score distribution for family members in the first 50 proteins. Protein scores are derived from ions scores as a non-probabilistic basis for ranking protein families.

Dupes Expect Rank U 1 2 Peptide
0.037 +2 GAYSLSLR significant
9 +1 GFFLFVEGGR top ranking
6.4e-005 +1 GSSIFGLAPGK significant and top ranking
1.3e-006 +1 X SSGTSYPDVLK peptide is found in all proteins in family member 1
6.2e-007 +1 / VCNYVSWIK peptide is found in some but not all proteins in family member 2
6.4e-005 +1 U GSSIFGLAPGK unique
+2 5.7e-005 +1 LNTLETEEWFFK peptide has two duplicates
0.18 +1 LNTLETEEWFFK duplicate peptide

Right-facing triangle (+) in the Dupes or Rank column indicates content that can be expanded by clicking on it. Down-facing triangle (-) indicates the content is expanded and can be collapsed. For more details about particular columns, see results format help.
