GlobalStd algorithm with structure/reaction directed analysis

Description

GlobalStd algorithm with structure/reaction directed analysis

Usage

globalstd(list, rtcutoff = 10, ng = 10, corcutoff = NULL,
  freqcutoff = 10, top = 50, digits = 2, accuracy = 4)

Arguments

list

a peaks list with mass to charge, retention time and intensity data

rtcutoff

cutoff of the distances in cluster, default 10

ng

cutoff of global PMD's retention time group numbers

corcutoff

cutoff of the correlation coefficient, default NULL

freqcutoff

cutoff of frequency of PMDs between RT cluster for independent peaks, default 10

top

top n pmd freqency cutoff when the freqcutoff is too small for large data set, default 50

digits

mass or mass to charge ratio accuracy for pmd, default 2

accuracy

measured mass or mass to charge ratio in digits, default 4

Value

list with GlobalStd algorithm processed data.
