Dear Dehghan,

It seems to me that your work would be easier if you had chosen
AutodockTools to prepare your input files for calculation with Autodock.
That GUI was designed for that. At first, you will have to generate a
grid parameter file (gpf) to be used by Autogrid. Among other
informations, you will have to write in such gpf file the coordinates of
your grid box center (in Angstrons) and the size of your grid box (in
points). After the Autogrid calculation, which is very fast, you will
have to generate a docking parameter file (dpf) that will be used by
Autodock, together with the output of Autogrid. Both gpf and dpf can be
easily generated by Autodocktools.

   Most likely AutoDock doesn't use the same coordinate system
that you're assuming in your email below.
