In michaelwitting/masstrixR: Annotation of MS based metabolomics data
View source: R/MS2_SpectrumDbSearch.R
Description
Function to find MS2 spectra in a MS2 library for spectral matching. The search parameters are a given precursor m/z and potentially its type of adduct.
Usage
1
2
searchByPrecursor(precursorMz, ms2dbFileName, mzTol = 0.005,
mzTolType = "abs", precursorType = NA)
Arguments
precursorMz
Mass of precursor for search
ms2dbFileName
File name or path to MS2 database
mzTol
Maximum allowed tolerance in Da or ppm
mzTolType
Defines the error type for m/z search, "abs" is used for absolute mass error, "ppm" for relative error
precursorType
String indicating the potential precursor adducts
