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 > 20 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.
