Calculate the covariance matrix from a normal mode object.
# S3 method for nma
cov(nma)
# S3 method for enma
cov(enma, ncore=NULL)Returns the calculated covariance matrix (function cov.nma), or
covariance matrices (function cov.enma).
an nma object as obtained from function
nma.pdb.
an enma object as obtained from function
nma.pdbs.
number of CPU cores used to do the calculation.
ncore>1 requires package ‘parallel’ installed.

This function calculates the covariance matrix from a nma
object as obtained from function nma.pdb or covariance matrices
from a enma object as obtain from function nma.pdbs.
