Assignment-directed Data collection Algorithm utilizing a Probabilistic Toolkit in NMR: a fully automated method for integration of optimized protein NMR data collection, chemical shift assignment, and secondary structure determination. PUBLICATION

ADAPT-NMR Enhancer

Software for visualization and analysis of tilted plane spectra derived from ADAPT-NMR. PUBLICATION


ARECA (Assessment of the REliability of Chemical shift Assignments): A probabilistic validation of protein NMR chemical shift assignments against NOESY data . PUBLICATION


High-resolution Iterative  Frequency Identification for NMR: an adaptive approach for rapid and automated collection of NMR data. PUBLICATION


Linear Analysis of Chemical Shifts: a method for detection and automated correction of potential referencing problems and detection of inconsistent assignments  - now included in PINE! PUBLICATION


Spectral analysis of multidimensional NMR data useful for complex mixtures. Newton implements a Fast Maximum Likelihood Reconstruction (FMLR) of NMR spectra from spectral deconvolution of raw data that constructs the simplest time-domain model whose fourier processed spectrum most closely matches the spectrum of the identically processed FID. PUBLICATION


High throughput data acquisition for Bruker NMR spectrometers running Topspin >2.0, fitted with ATM and SampleJet hardware accessories. PUBLICATION


SPARKY supports user-defined enhancements, and we have used these to develop new tools in support of our packages for automated protein assignment and structure determination. The added features support (1) interfacing with servers offering new technologies, (2) tools for data visualization and verification, and (3) new protocols for maximizing the efficiency of NMR data analysis. PUBLICATION
 NMR Structure Tools
 A PyMol add-on with tools for NMR structure ensemble analysis such as pairwise alignment, structure restraint validation and hydrogen-bond detection.


Protein structure And Chemical Shift NMR spectroscopY: a relational database management system that integrates information from the Protein Data Bank (PDB), the Biological Magnetic Resonance Data Bank (BMRB), and the Structural Classification of Proteins (SCOP) database. PUBLICATION


Protein Energetic Conformational Analysis from NMR chemical shifts: probabilistic secondary structure predictions from chemical shift– now included in PINE! PUBLICATION


Probilistic Interaction Network of Evidence: a probabilistic algorithm for automated backbone and sidechain assignments, with detection and correction of referencing and secondary structure determination from input protein sequence and NMR data set peak lists. PUBLICATION


SPARKY extension for the manual verification of PINE automated assignments. Now included in the NMRFAM-SPARKY Distribution. PUBLICATION



Peak picking Of NOE Data Enabled by Restriction Of Shift Assignments: a program for protein structure determination that utilizes information from prior assignments to automatically pick NOE peaks from 3D-NOESY (13C-edited and 15N-edited) spectra, with results used as input for a series of CYANA structure calculations. PUBLICATION

PONDEROSA-C/S builds on the original PONDEROSA software and includes improved features for structure calculation and refinement in client-server model. PUBLICATION


RNA Probabilistic Assignment of Imino Resonance Shifts: a probabilistic algorithm for the automated assignment of RNA imino 1H and 15N resonances shifts, with conjoined determination and validation of secondary structure from input RNA sequence, and 1H-1H 2D-NOESY and 1H-15N 2D-HSQC spectra peak lists. PUBLICATION


An open source software package for visualizing and interpreting one and two dimensional NMR data specifically designed for high-throughput assignment and quantification of small molecules. Supports extensive batch manipulation of plotting parameters and has numerous tools for expediting repetitive resonance assignment and quantification tasks. PUBLICATION

NMRFAM Script Library

A collection of scripts for NMR spectroscopists and general macromolecular structure research.
NMRFAM Virtual Machine

Ubuntu Mate based Virtual Machine (VM) with pre-installed the latest versions of NMRFAM-Sparky, PyMOL, PONDEROSA-C/S packages.

A VM is an emulation of a computer operating system that can be installed and run on any different operating system. NMRFAM's VM runs the Linux operating system Ubuntu. To run this on your Windows, Mac, or Linux computer, you will need to install VirtualBox (a virtualization software package from Oracle, freely available at www.virtualbox.org). You MUST have administrative privileges to install VirtualBox on your computer. For PCs, VirtualBox requires the enabling of virtualization in the BIOS.


A tool for the optimization of compound mixtures in 1D 1H NMR ligand affinity screens. PUBLICATION
