covsoverlap: Covariance Overlap

Description

Calculate the ovariance overlap obtained from NMA.

Usage

covsoverlap(...)
## S3 method for class 'enma':
covsoverlap(enma, ncore=NULL, ...)
## S3 method for class 'nma':
covsoverlap(a, b, subset=NULL, ...)

Arguments

enma
an object of class "enma" obtained from function nma.pdbs.
ncore
number of CPU cores used to do the calculation. ncore>1 requires package parallel installed.
a
a list object with elements U and L (e.g. as obtained from function nma) containing the eigenvectors and eigenvalues, respectively, to be compared with b.
b
a list object with elements U and L (e.g. as obtained from function nma) containing the eigenvectors and eigenvalues, respectively, to be compared with a.
subset
the number of modes to consider.
...
arguments passed to associated functions.

Value

  • Returns the similarity coefficient(s).

Details

Covariance overlap is a measure for the similarity between two covariance matrices, e.g. obtained from NMA.
