Constructor & Destructor Documentation

   IsoSpec::Iso::Iso ()
       Definition at line 50 of file isoSpec++.cpp.

   IsoSpec::Iso::Iso (int _dimNumber, const int * _isotopeNumbers, const int * _atomCounts, const
       double * _isotopeMasses, const double * _isotopeProbabilities)
       General constructror.

       Parameters
           _dimNumber The number of elements in the formula, e.g. for C100H202 it would be 2, as
           there are only carbon and hydrogen atoms.
           _isotopeNumbers A table with numbers of isotopes for each element, e.g. for C100H202
           it would be {2, 2}, because both C and H have two stable isotopes.
           _atomCounts Number of atoms of each element in the formula, e.g. for C100H202
           corresponds to {100, 202}.
           _isotopeMasses A table of tables of masses of isotopes of the elements in the chemical
           formula, e.g. {{12.0, 13.003355}, {1.007825, 2.014102}} for C100H202.
           _isotopeProbabilities A table of tables of isotope frequencies of the elements in the
           chemical formula, e.g. {{.989212, .010788}, {.999885, .000115}} for C100H202.

Member Function Documentation

   void IsoSpec::Iso::addElement (int atomCount, int noIsotopes, const double * isotopeMasses,
       const double * isotopeProbabilities)
       Add an element to the molecule. Note: this method can only be used BEFORE Iso is used to
       construct an IsoGenerator instance.

       Definition at line 324 of file isoSpec++.cpp.

   bool IsoSpec::Iso::doMarginalsNeedSorting () const [protected]

   Iso IsoSpec::Iso::FromFASTA (const char * fasta, bool use_nominal_masses = false, bool
       add_water = true) [static]
       Constructor (named) from aminoacid FASTA sequence as C string.

       Parameters
           fasta An aminoacid FASTA sequence. May be upper/lower/mixed case, may contain
           selenocystein (U) or xleucine (J). Other characters, including FASTA codes of
           indeterminate chemical formula (X, *, -, B, ...) are silently ignored. That means
           'AEDA', 'AE-DA', 'EAXXDA', 'AE DA' will all result in the same chemical formula.
           Subisotopologues will be in order: CHNOS, possibly with Se added at an end if present.
           \use_nominal_masses Whether to use nucleon number instead of the real mass of each
           isotope during calculations. \add_water Whether the chain should have the terminating
           -H and -OH groups at the N and C terminus, respectively.
