Member Function Documentation

getBinNumber()

static uint getBinNumber ( double  qscore, uint  total_bin_number  )

staticprivate

get a bin number given qvalue. qvalue is calculated per bin (bin from 0 to 1).

getDistribution()

static std::vector<double> getDistribution ( const std::vector< double > &  qscores, uint  bin_number  )

staticprivate

get the setQscore distribution

getDistributionWeights()

static std::vector<double> getDistributionWeights ( const std::vector< double > &  mixed_dist, const std::vector< std::vector< double >> &  comp_dists, uint  num_iterations = 100  )

staticprivate

get the weights of different dummy types.

updatePeakGroupQvalues()

static void updatePeakGroupQvalues ( std::vector< DeconvolvedSpectrum > &  deconvolved_spectra )

static

Calculate and perform a batch update of peak group qvalues using Qscores of target and dummy peak groups in deconvolved spectra, when FDR report is necessary.

Parameters

deconvolved_spectra

target and decoy deconvolved spectra
