Here, we will endeavor to present definitions for measuring protein volume, showing how they are related to various definitions of linear distance (VDW parameters) and surface. Further information related to macromolecular geometry, focussing on volumes, is available from: http://bioinfo.mbb.yale.edu/geometry. Definitions of Protein Volume.
More generally, a distance geometry description of a molecular system consists of a list of distance and chirality constraints. These are, respectively, lower and upper bounds on the distances between pairs of atoms, and the chirality of its rigid quadruples of atoms (i.e., R or S relative to some given order).
14 lip 2017 · Currently, the most prominent application of distance geometry is related to molecular geometry. Specifically, the problem is the calculation of the 3D protein structure using distance information obtained from Nuclear Magnetic Resonance (NMR) experiments [ 79, 80 ].
1 sty 2012 · In the very first works on this topic [3, 9], the term distance geometry described this procedure, checking the consistency of a set of distance intervals. Only later it became the preprocessing step for the following structure generation step.
Equations for genetic distances: Download a pdf of equations for various measures of genetic distance. This pdf was once on the NC State website (statistical genetics home base for Weir and Cockerham). http://statgen.ncsu.edu/brcwebsite/software_BRC.php
• Distance can be abstract R≥0-valued or physical (as length): between spatial or temporal points (the length of journey till, say, speed or concentration reach fixed value). • Usually, several distances on the same data should be compared. • Distance/similarity can be implicite as in Clustering.
1 lis 2013 · Distance geometry is a class of problems where the position of points in space is to be identified by using information about some relative distances between these points.
