Software

We develop a series of software programs for NMR data processing, analysis and education, collectively known as the NMR Zoo. All these programs are free to use and open-source. We welcome feedback and questions, which you can place on our gitlab repositories or send to ssnake@science.ru.nl.

ssNake

NMR processing and fitting software

ssNake is a versatile, cross-platform, open source NMR data processing and analysis program, with a particular focus on solid state NMR.

Windows Installer: ssNake v1.5 Installer Windows 64bit (exe, 67 MB)
MacOS: Visit the gitlab page below for more information
Python code: ssNake v1.5 python source (zip, 3.4 MB)

Magpie

Virtual NMR spectrometer

Magpie is a virtual liquid state NMR spectrometer based on the Bloch equations. It can be used for the initial training of students on e.g. setting adequate acquisition parameters, calibrating pulses, and determining relaxation times.

Windows Installer (beta version): Magpie v0.0 Installer Windows 64bit (exe, 58 MB)
MacOS: Visit the gitlab page below for more information
Python code: Magpie v0.0 python source (zip, 0.8 MB)

Shimpanzee

Shimming simulator

Shimpanzee is a program to teach students about shimming. It simulates spectral lineshapes as a function of shim settings and rotor angle.

Windows executable: Shimpanzee Windows 64bit (zip, 57 MB)
Python code: Shimpanzee source (zip, 0.1 MB)
Source code repository: https://gitlab.science.ru.nl/mrrc/nmrzoo/shimpanzee

Jellyfish

J-coupling simulator

Jellyfish is a program to teach students about J-coupling. It simulates weak and strong J-coupling in spectra of isotropic spin systems.

Windows executable: Jellyfish Windows 64bit (zip, 57 MB)
Python code: Jellyfish python source (zip, 0.1 MB)
Source code repository: https://gitlab.science.ru.nl/mrrc/nmrzoo/jellyfish

Tiger

NMR periodic table

A small program that provides an interactive NMR periodic table with detailed information per NMR-active isotope. It is also incorporated into ssNake.

Python code: Tiger python source (zip, 0.1 MB)
