GetAvgSpectrum: Get averaged spectrum

In Yaroslav-Lyutvinskiy/MZAccessR: R Interface to mzAccess Web-API

Description

Get spectrum averaged (or summed) within RT interval Corresponds to mzAccess web-service API function GetAverageSpectrum Averaging algorithm is vendor specific, therefore function has no cache option

Usage

GetAvgSpectrum(FileName, MZLow, MZHigh, RTLow, RTHigh, Profile = FALSE)

Arguments

FileName	- Name of original raw mass spectrometry file. Can be stated with or without path and extention
MZLow	- Minimum m/z value to be included in spectrum
MZHigh	- Maximum m/z value to be included in spectrum
RTLow	- Minimum retention time value for RT range of averaged spectrum
RTHigh	- Maximum retention time value for RT range of averaged spectrum
Profile	- If TRUE data will presented in profile mode how is was acquired by mass spectrometer, If FALSE data will be presented in peak centroided mode

Value

Data frame of Mass and Intensities for requested LC-MS area

Examples

GetAvgSpectrum("Thermo_QE_cells_72h_LA_3", MZLow = 50, MZHigh = 400, RTLow = 6, RTHigh = 8, Profile = FALSE)
