Python: module pairDist

pairDist

Class to generate a pairwise distance distribution and the associated gradients with respect to atomic coordinates. Constructor: PairDist(rVals, atomSel1, atomSel2, weights1, weights2, probWidth=0.5, probType="quartic", calcGradient=False) rVals - an array containing a uniform grid of distance values atomSel1, atomSel2 - atomSel.AtomSel objects containing the atoms whose positions are sed to generate the distance distribution. weights1, weights2 - arrays specifying weights for atoms in atomSel1 and and atomSel2, repsectively. probWidth - the width of the probability distribution contribution from a single pair of atoms. probType - a string describing the type of probability distribution. Currently, only "quartic" is accepted. calcGradient - specifies whether the gradient is calculated. Members: Accessors: weights1() weights2() - return/set weights. If normalize==True, setWeights1/2 will normalize input weights. probWidth - probWidth, as specified in the constructor. probType - as specified in the constructor. calcGradient - a specified in the constructor. calcWeightDerivs - calculate derivative of Pr with respect to weights1 and weights2, If True, the values are stored in the members d_dw1 and d_dw2, respectively. These are two- dimensional arrays with the first dimension denoting the atom specified in the respective atomSel, and the second specifying bin number. normalize - by default, the probability distribution is normalized by the product of the sums of the two weights arrays. Set normalize to False to disable this normalization. Methods: updateValues() - force a recalculation of the P(r) (and gradient, if the current value of calcGradient is True). Pr() - return an array containing the pairwise distance distribution the distance at the center of each bin corresponding to the associated value of rVals. Computed as <string>

Pr(r) = 1 ⁄ N∑_i, jw_iw_jPr_i, j(|q_i − q_j| − r) where the sum is over two sets of atoms with positions q_i and q_j, and associated weights w_i and w_j.

/ N_P (r^2 - r_c^2)^2 , for r<r_c Pr_{i,j}(r) = | \ 0 , for r>=r_c <string> where r_c is the probWidth member value, and N_P = 105 ⁄ (32πr⁷_c) The value N = 1 ⁄ (Δr∑_iw_i∑_jw_j), where Δr is the grid spacing of rVals, unless normalize=False, in which case N = 1 ⁄ Δr. getGradient(binNum) - return a list of (index,Vec3) pairs specifying all of the gradient contributions to binNum of the distance distribution. removeAtoms1(sel) - remove the atoms from the PairDist - specified by an removeAtoms2(sel) atomSel.AtomSel argument, along the the associated weight(s). # This file was automatically generated by SWIG (http://www.swig.org). # Version 4.0.2 # # Do not make changes to this file unless you know what you are doing--modify # the SWIG interface file instead.
