DYNAMICS, RELAXFIT & ROTDIF, programs for analysis of 15N NMR relaxation experiments, are currently available for download from the website of Dr. Fushman's group . Below are the software description and references that were borrowed from Dr. Fushman's website.
RELAXFIT
A program for extracting relaxation rates (e.g. R1 or R2) from fitting experimental data to an exponentially decaying function.
Reference: Fushman et al., J. Mol. Biol. 266 (1997) 173.
DYNAMICS
A program for model-free analysis of 15N relaxation data.
Features isotropic, axially-symmetric and fully anisotropic models for the overall tumbling of the molecule, and monomer-dimer equilibration.
Reference: Fushman et al., J. Mol. Biol. 266 (1997) 173; Hall & Fushman, J. Biomol. NMR
ROTDIF
A program for the determination of the overall rotational diffusion tensor of a molecule from spin-relaxation data.
Features isotropic, axially-symmetric, and fully anisotropic models for the overall motion.
Reference: Fushman et al., Biochemistry 38 (1999) 10225-10230; Varadan et al., JMB 324 (2002) 637; Walker et al. J. Magn. Reson. (2004) 168, 336; Fushman et al, Progress NMR Spectroscopy, (2004) 44, 189.
