Usage

orbi_read_isox(file)

Arguments

file

Path to the .isox file

Value

A tibble containing at minimum the columns filename, scan.no, time.min, compound, isotopocule, ions.incremental, tic, it.ms

Details

Additional information on the columns:

  • filename: name of the original Thermo .raw file processed by IsoX

  • scan.no: scan number

  • time.min: acquisition or retention time in minutes

  • compound: name of the compound (e.g., NO3-)

  • isotopocule: name of the isotopocule (e.g., 15N); called isotopolog in .isox

  • ions.incremental: estimated number of ions, in increments since it is a calculated number

  • tic: total ion current (TIC) of the scan

  • it.ms: scan injection time (IT) in millisecond (ms)

fpath <- system.file("extdata", "testfile_dual_inlet.isox", package = "isoorbi")
df <- orbi_read_isox(file = fpath)
