Molecular dynamics re-refinement of two different small RNA loop structures using the original NMR data suggest a common structure
Abstract Restrained molecular dynamics simulations are a robust, though perhaps underused, tool for the end-stage refinement of biomolecular structures. We demonstrate their utilityâ??using modern simulation protocols, optimized force fields, and inclusion of explicit solvent and mobile counterionsâ??by re-investigating the solution structures of two RNA hairpins that had previously been refined using conventional techniques. The structures, both domain 5...

Knowledge-based nonuniform sampling in multidimensional NMR
Abstract The full resolution afforded by high-field magnets is rarely realized in the indirect dimensions of multidimensional NMR experiments because of the time cost of uniformly sampling to long evolution times. Emerging methods utilizing nonuniform sampling (NUS) enable high resolution along indirect dimensions by sampling long evolution times without sampling at every multiple of the Nyquist sampling interval. While the earliest NUS approaches matched the decay of sampling density to the decay of the signal envelope, recent...

Tips
It rarely happens to find valuable tips about processing on the web. When it happens, it's probably not enough to bookmark the page (it may disappear), copying it is a better idea. Here is the link:
http://spin.niddk.nih.gov/NMRPipe/embo/
When you arrive there, scroll down until you find the chapter Some General Tips About Spectral Processing.
The focus is on multi-dimensional processing with NMRPipe, but a few concepts are generally applicable indeed.
The brief discussion about first-point pre-multiplication is something to bear in mind. You can also find clearly expressed...
