The `mrinversion` python package is based on the statistical learning technique for determining the underlying distribution of the magnetic resonance (NMR) parameters.

The library utilizes the [mrsimulator](https://mrsimulator.readthedocs.io/en/latest/)
package for generating solid-state NMR spectra and
[scikit-learn](https://scikit-learn.org/latest/) package for statistical learning.

## Features

The `mrinversion` package includes

- **Spectral Inversion**: Two-dimensional solid-state NMR spectrum of dilute spin-systems correlating
  the isotropic to anisotropic frequencies to a three-dimensional distribution of NMR tensor parameters.
  Presently, we support the inversion of

- **Magic angle turning (MAT), Phase adjusted spinning sidebands (PASS)**, and similar
    spectra correlating the isotropic chemical shift resonances to pure anisotropic
    spinning sideband resonances into a three-dimensional distribution of
    nuclear shielding tensor parameters---isotropic chemical shift, shielding
    anisotropy and asymmetry parameters---defined using the Haeberlen convention.

- **Magic angle flipping (MAF)** spectra correlating the isotropic chemical shift
    resonances to pure anisotropic resonances into a three-dimensional distribution of
    nuclear shielding tensor parameters---isotropic chemical shift, shielding
    anisotropy and asymmetry parameters---defined using the Haeberlen convention.

- **Relaxometry Inversion**: Inversion of NMR relaxometry measurements to the distribution of
  relaxation parameters (T1, T2).
