HashMap<Integer,String[]> |
getSurroundingAA(String peptide,
int nAA,
SequenceMatchingPreferences sequenceMatchingPreferences)
Returns the amino acids surrounding a peptide in the sequence of the
given protein in a map: peptide start index > (amino acids before,
amino acids after).
|
boolean |
isCTerm(String peptideSequence,
SequenceMatchingPreferences sequenceMatchingPreferences)
Returns a boolean indicating whether the protein ends with the given
peptide.
|
boolean |
isDecoy()
Indicates if the protein is factice (from a decoy database for instance).
|
boolean |
isEnzymaticPeptide(String peptideSequence,
Enzyme enzyme,
SequenceMatchingPreferences sequenceMatchingPreferences)
Returns true of the peptide is non-enzymatic, i.e., has one or more end
points that cannot be caused by the enzyme alone.

boolean |
isNTerm(String peptideSequence,
SequenceMatchingPreferences sequenceMatchingPreferences)
Returns a boolean indicating whether the protein starts with the given
peptide.
|
boolean |
isSameAs(Protein anotherProtein)
A method to compare proteins.
