getpaired | R Documentation |
Filter ions/peaks based on retention time hierarchical clustering, paired mass distances(PMD) and PMD frequency analysis.
getpaired(
list,
rtcutoff = 10,
ng = NULL,

mdrange = NULL
)
list |
a list with mzrt profile |
rtcutoff |
cutoff of the distances in retention time hierarchical clustering analysis, default 10 |
ng |
cutoff of global PMD's retention time group numbers, If ng = NULL, 20 percent of RT cluster will be used as ng, default NULL. |
digits |
mass or mass to charge ratio accuracy for pmd, default 2 |
accuracy |
measured mass or mass to charge ratio in digits, default 4 |
mdrange |
mass defect range to ignore. Default NULL and c(0.25,0.9) to retain the possible reaction related paired mass |
list with tentative isotope, multi-chargers, adducts, and neutral loss peaks' index, retention time clusters.
