a program for the automated structure calculation of biological macromolecules on the basis of conformational constraints from NMR.

CYANA is a commercial software application that we can include in your installation for ease of use, but that requires you or your institute to have a current license in place. To enable the SBGrid installation for CYANA please send an email to licensing@sbgrid.org ...

The basic hydrodynamic quantities involved in dynamic NMR are evaluated in the same fashion as in the closely related HYDROPRO program. HYDRONMR then calculates NMR quantities, like T1, T2, NOE,. for each residue of a globular ...
an algorithm to reconstruct non-uniformly acquired NMR data.
(Multiscale Modeling Tools for Structural Biology) a collection of perl-based user-level utilities as well as programming libraries for multiscale protein structure modeling. Intended applications include protein structure prediction, loop modeling, structure refinement, and structure evaluation/scoring.
a program to fit the extended model free spectral density function to NMR spin relaxation data. The program can analyze the spin-lattice relaxation rate constant (R1), the spin-spin relaxation rate constant (R2), and the heteronuclear steady-state {1H}-X nuclear Overhauser effect (NOE) for any combination of 13C and 15N spins at up to five static magnetic fields.
a novel program developed to allow the determination of alignment tensor parameters for individual or multiple domains in macromolecules from residual dipolar couplings and to facilitate their manipulation and construct low-resolution models of macromolecular structure.
an open source software to analyse NMR relaxation dispersion data of either CPMG or R1p (R1rho) dispersion experiments. The graphical interface enables simple management of large experimental data sets and simple and automated analysis. NESSY autamatically calculates effective transverse relaxation rate (R2eff) and performs model selection between different relaxation dispersion models.
is a new version of Sparky renamed because NMRFAM has taken over the original Sparky to support advances in the biomolecular NMR field. Tom Ferrin and Tom Goddard of UCSF, generously allowed NMRFAM to develop this the original Sparky, which remains the most popular NMR biomolecular analysis tool available.
