...if so, check programs from
Prof. Llinas's lab:
MIDGE, CLOUDS, SPI, BACUS and ABACUS.
A brief description of the program, that was copied from the Prof. Llinas's website:
************************************************** ***********
"MIDGE: Model-independent refinement of interproton distances generated from h-1-nmr overhauser intensities
CLOUDS: Protein structure elucidation from NMR proton densities.
SPI: a Bayesian protocol for uncovering spin systems.
BACUS: A Bayesian protocol for the identification of protein NOESY spectra via unassigned spin systems.
ABACUS: a Direct Method for Protein NMR Structure Computation via Assembly of Fragments"
