MS1MatchSpectra: MS1featureMatch

In WMBEdmands/compMS2Miner: an automatable metabolite identification, visualization and data-sharing R package for high-resolution LC-MS datasets

Description

match ms1 features defined by mz and Rt to vector of ms2 features

Usage

MS1MatchSpectra(metaData = NULL, MS2file = NULL, mz = NULL, RT = NULL,
  EIC = NULL, adduct = NULL, precursorPpm = 10, ret = 10,
  adducts = FALSE, isoWid = 4)

Arguments

mz	mass to charge ratio (from the MS1 peak table).
RT	retention time in seconds (from the MS1 peak table).
precursorPpm	parts per million mass accuracy for match (default
ret	retention time window (+/- seconds) for match
isoWid	isolation width of ions.
mz.v	numeric vector of mass to charge ratio (from MS2 precursors)
RT.v	numeric vector of retention time in seconds (from MS2 precursors)

Value

returns indices of matches as a list object
