Weba numeric matrix of atom-wise cross-correlations as output by the ‘dccm’ function. resno. an optional vector with length equal to that of x that will be used to annotate the x- and y-axis. This is typically a vector of residue numbers. Can be also provided with a ‘pdb’ object, in which ‘resno’ of all C-alpha atoms will be used. WebDec 12, 2002 · The angle brackets denote an ensemble average. The elements C(i, j) can be collected in matrix form and displayed as a three-dimensional dynamical cross-correlation map (DCCM) . There is a time scale implicit in the C(i, j). The cross correlation was calculated as block average over time from 500 ps to 10 ns from the MD trajectory.
WebOct 27, 2024 · dccm is a generic function calling the corresponding function determined by the class of the input argument x. Use methods ("dccm") to get all the methods for dccm generic: dccm.xyz will be used when x is a numeric matrix containing Cartesian coordinates (e.g. trajectory data). dccm.pca will calculate the cross-correlations based on an pca object. WebAug 4, 2004 · Abstract. We propose a model of coupled random walks for stock-stock correlations. The walks in the model are coupled via a mechanism that the …
WebHi All, I have been trying to evaluate the dynamical cross correlation matrix or commonly known as cross-correlation matrix from a trajectory. The g_covar program gives the cross-covariance matrix as covara.xpm. However, that's not what I want to estimate. I want to calculate the C-alpha based cross-correlation matrix where the correlation ...
