Do anyone know how to calculate the coordinates of the atoms of
the backbone from phi and psi angles?
We got a short C program that calculates phi-psi angles from
Brookhaven protein data files but we need to do the reverse:
we are trying to simulate the folding process and we need to
model how changing the phi-psi angles affect the protein shape.
thanks in advance
