Grid computing for improving conformational sampling in NMR structure calculation.

Bioinformatics. 2011 May 5;

Authors: Mareuil F, Blanchet C, Malliavin TE, Nilges M

MOTIVATION: Methods for automatic NMR structure determination need to face a high level of ambiguity encountered in NMR spectra recorded by solid-state NMR and by solution NMR of partially unfolded proteins, leading to time-consuming calculations. The software package Ambiguous Restraints for Iterative Assignment (ARIA) allows for straightforward parallelization of the calculation, as the conformers can be generated in parallel on many nodes. RESULTS: Due to its architecture, the adaptation of ARIA to grid computing can be easily achieved by using the middleware glite and JDL (Job Description Language) scripts. This adaptation makes it possible to address highly ambiguous data sets, because of the much larger conformational sampling that can be generated by use of the grid computational power. AVAILABILITY: The version 2.3.1 of ARIA implemented on the grid is freely available from the ARIA Web site: aria.pasteur.fr/downloads. CONTACT: Michael Nilges: nilges@pasteur.fr.
