base-analysis

Common package to deal with spectral analysis.

An Analysis may be composed of many Measurements of different flavors.

By default the flavor is an empty string and if your analysis only generates one spectrum you may forget this level of complexity.

In the case of Thermogravitational Analysis (TGA) we may have 2 flavor for the data:

• Weight versus Temperature
• Weight versus Time

This package allow to load / save an Analysis as a JCAMP-DX text file.

Installation

$ npm i base-analysis

Usage

import { Analysis, fromJcamp, toJcamp, getJSGraph } from '..';

let analysis = new Analysis();
expect(analysis.id).toHaveLength(8);

analysis.pushMeasurement(
  { x: [1, 2], y: [3, 4] },
  {
    xUnits: 'xUnits',
    yUnits: 'yUnits',
    xLabel: 'X axis',
    yLabel: 'Y axis',
    title: 'My spectrum',
    dataType: 'TGA',
    meta: {
      meta1: 'Meta 1',
      meta2: 'Meta 2',
    },
  },
);

let firstAnalysis = analysis.getMeasurement();

let normalized = analysis.getNormalizedMeasurement({
  normalization: {
    filters: [{ name: 'normed' }],
  },
});

let jsgraph = getJSGraph([analysis]);

let jcamp = toJcamp(analysis, {
  info: {
    owner: 'cheminfo',
    origin: 'Base analysis',
  },
});

let analysis2 = fromJcamp(jcamp);
