AlpsNMR-package: AlpsNMR: Automated spectraL Processing System for NMR

In AlpsNMR: Automated spectraL Processing System for NMR

Description

AlpsNMR allows you to import NMR spectra into R and provides automated and efficient signal processing for untargeted NMR metabolomics.

Details

The following functions can be combined with the pipe. They create or modify the nmr_dataset object.

• nmr_read_samples_dir() or nmr_read_samples()

• nmr_interpolate_1D()

• nmr_exclude_region()

• nmr_normalize()

• plot()

There are also functions to extract the metadata and submit the samples to irods, see the example below.

The nmr_dataset object is essentially a list, so it is easy to access its components for further analysis.
