In enviGCMS: GC/LC-MS Data Analysis for Environmental Science

Combine two data with similar retention time while different mass range

Description

Combine two data with similar retention time while different mass range

Usage

cbmd(data1, data2, mzstep = 0.1, rtstep = 0.01)

Arguments

data1	data file path of lower mass range
data2	data file path of higher mass range
mzstep	the m/z step for generating matrix data from raw mass spectral data
rtstep	the alignment accuracy of retention time, e.g. 0.01 means the retention times of combined data should be the same at the accuracy 0.01s. Higher rtstep would return less scans for combined data

Value

matrix with the row as scantime in second and column as m/z

Examples

## Not run: 
# mz100_200 and mz201_300 were the path to the raw data
matrix <- getmd(mz100_200,mz201_300)

## End(Not run)
