Method Detail

getMDScore

public static java.lang.Double getMDScore(SpectrumMatch spectrumMatch,
                          java.util.ArrayList<java.lang.String> ptms,
                          AminoAcidPattern.MatchingType matchingType,
                          java.lang.Double massTolerance)

Returns the MD score for the best peptide in a spectrum match (the best peptide has to be set before). Null if not identified by Mascot. If the peptide is the not the best scoring for Mascot the score will be negative.

Parameters:

spectrumMatch - the spectrum match of interest

ptms - the names of the PTMs to score

matchingType - the amino acid matching type

massTolerance - the mass tolerance for matching type 'indistiguishibleAminoAcids'. Can be null otherwise

Returns:

the MD score

getMDScore

public static java.lang.Double getMDScore(SpectrumMatch spectrumMatch,
                          Peptide peptideCandidate,
                          java.util.ArrayList<java.lang.String> ptms,
                          AminoAcidPattern.MatchingType matchingType,
                          java.lang.Double massTolerance)

Returns the MD score for the given peptide in a spectrum match. Null if not identified by Mascot. If the peptide is the not the best scoring for Mascot the score will be negative.

Parameters:

peptideCandidate - the peptide of interest

spectrumMatch - the spectrum match of interest

ptms - the names of the PTMs to score

matchingType - the amino acid matching type

massTolerance - the mass tolerance for matching type 'indistiguishibleAminoAcids'. Can be null otherwise

Returns:

the MD score
