Public Member Functions inherited from IsoSpec::Iso
Iso (int _dimNumber, const int *_isotopeNumbers, const int *_atomCounts, const double *_isotopeMasses, const double *_isotopeProbabilities)
General constructror. Iso (int _dimNumber, const int *_isotopeNumbers, const int *_atomCounts, const double *const *_isotopeMasses, const double *const *_isotopeProbabilities)
Iso (const char *formula, bool use_nominal_masses=false)
Constructor from the formula object. Iso (const std::string &formula, bool use_nominal_masses=false)
Constructor from C++ std::string chemical formula. Iso (Iso &&other)
The move constructor. Iso & operator= (const Iso &other)=delete
Iso (const Iso &other, bool fullcopy)
The copy constructor. virtual ~Iso ()
Destructor. double getLightestPeakMass () const
Get the mass of the lightest peak in the isotopic distribution. double getHeaviestPeakMass () const
Get the mass of the heaviest peak in the isotopic distribution. double getMonoisotopicPeakMass () const
double getModeLProb () const
Get the log-probability of the mode-configuration (if there are many modes, they share this value). double getUnlikeliestPeakLProb () const
Get the logprobability of the least probable subisotopologue. double getModeMass () const
Get the mass of the mode-configuration (if there are many modes, it is undefined which one will be selected). double getTheoreticalAverageMass () const
Get the theoretical average mass of the molecule. double variance () const
Get the theoretical variance of the distribution. double stddev () const
Get the standard deviation of the theoretical distribution. int getDimNumber () const
Get the number of elements in the chemical formula of the molecule. int getAllDim () const
Get the total number of isotopes of elements present in a chemical formula. void addElement (int atomCount, int noIsotopes, const double *isotopeMasses, const double *isotopeProbabilities)
