The variable is ntx. The value "7" is the same as "5", although 5 is the
only one documented in the Amber manual, IIRC. And this is not for reading
the box information, it's specifying whether or not velocities are present
in the inpcrd file. If velocities are present, you should use ntx=5 (or
7). If they are not present (e.g., following a minimization), set ntx=1.
The box information will always be looked for if it's needed (and found if
it's present).
