Dear NAMD users
I want to get the tilted angle of protein.
So, I using tilt component in colvars module.
My colvars configuration file is below:
atomNameResidueRange CA 1-8
refPositionsFile ../colvars_orient/pdb file
I have some question.
1. I know the value of lowerboundary, upperboundary, centers and
targetcenters are cosine(theta).
but what is value of the width??
I guess the value of width: the angle of degree? or radian? or other
well, I put the degree, In my colvars configuration file.
2. The harmonic oscillator is k(x - x_0).
But, I don't know x. x is theta? or cosine(theta)?
Thanks for reading.
