Dear gromacs users, I am trying to figure out the meaning of the cmaptypes section in file section. As far as I understood, taking the following entry as example: C NH1 CT1 C NH1 1 24 24\ C NH1 CT1 C = phi H1 CT1 C NH1 = psi 24*24 = dimension of the grid My question is: what does the 1 mean? Best, Francesco
