sci-chemistry jlec@gentoo.org PRODECOMP (PROjection DECOMPosition) is a software tool for decomposition of 2D projections of high-dimensional NMR spectra to a set of components (defined in turn by one-dimensional "shapes"). Simultaneous analysis of projections from one or several high-dimensional experiments provide unambigous chemical shifts for large spin systems. The latter can be used for backbone and side-chain assignments as well as structural studies of proteins (Malmodin and Billeter 2005; 2006; Staykova et al. 2008a,b).
