Calculate the variance of all pairwise distances in an ensemble of Cartesian coordinates.
var.xyz(xyz, weights=TRUE) var.pdbs(pdbs, ...)
an object of class
logical, if TRUE weights are calculated based on the pairwise distance variance.
a ‘pdbs’ object as object from function
arguments passed to associated functions.
This function calculates the variance of all pairwise distances in an ensemble of Cartesian coordinates. The primary use of this function is to calculate weights to scale the pair force constant for NMA.
Returns the a matrix of the pairwise distance variance, formated as weights if ‘weights=TRUE’.
