Index for the sdENM ff
A dictonary of spring force constants for the sdENM force field.
data(sdENM)
An array of 27 matrices containg the spring force constants for the ‘sdENM’ force field (see Dehouch et al for more information). Each matrix in the array holds the force constants for all amino acid pairs for a specific distance range.
See examples for more details.
