Open Source Software for NMR Data Analysis

Home Download Data Help Contact


rNMR is an open source software package for visualizing and interpreting one and two dimensional NMR data. In contrast to most existing 2D NMR software, rNMR is specifically designed for high-throughput assignment and quantification of small molecules. As a result, rNMR supports extensive batch manipulation of plotting parameters and has numerous tools for expediting repetitive resonance assignment and quantification tasks.

The most powerful features of rNMR are built around the region of interest (ROI) concept. ROIs are user-defined chemical shift ranges that can be used to visualize and analyze hundreds of NMR signals from multiple spectra simultaneously. Unlike peak tables, ROIs are dynamic representations of the underlying NMR data. Users can actively manipulate the chemical shift ranges of ROIs while simultaneously visualizing the impact these changes will have on resonance assignments and quantification of signals.
