Installation

$ npm install --save chromatography

Usage

import * as GCMS from 'chromatography';
// const GCMS = require('chromatography');

let gcms = GCMS.fromJcamp(jcampReferenceMixture);

let kovatsConversionTable = GCMS.getKovatsTable(gcms); // [{time, value}]
let conversionFunction = GCMS.kovatsConversionFunction(kovatsConversionTable, {});

let diesel = GCMS.fromJcamp(jcampOfDiesel);
let times = GCMS.rescaleTime(diesel.getTimes(), conversionFunction);
diesel.setTimes(times);
// diesel.rescaleTime(conversionFunction);

let peaks = GCMS.getPeaks(diesel, options);
let dieselJSON = diesel.toJSON(options); // [{time:12, height:12, width: 3, mass: [{mass, intensity}]}]
let gcms2 = GCMS.fromJSON(anotherDieselJSON);
let similarity = GCMS.similarity(gcms, gcms2, options);

// get a spectrum in another reference model
let revertConversionFunction = GCMS.kovatsConversionFunction(kovatsConversionTable, {revert: true});
let mySpectrumInAnotherReference = revertConversionFunction(mySpectrum);
