Dear Ed,

John is essentially correct. To use the MakePixFamily function, you
must have NTK version 1.6.4 (Mac) or 1.6.1 (Windows), and you must
use the Newton 2.1 platform Project Setting. Look in the Project menu
under Project Settings (at the bottom). Pick the Project Setting icon
and select "Newton 2.1" as the Platform.

But also note you have other troubles. When you look at the output of
the calibration generator (as shown in your listing of afterScript),
you have several NaNs. This is bad as NaN means "Not a Number."
Something has gone wrong with the calibration (usually a floating
point overflow/underflow). What, I don't know because I don't know
what your inputs were. Just remember it asks for latitude (N/S)
first, then longitude (E/W), and east longitudes are positive, west
longitudes (e.g., California) are negative.

Cheers,
-Mike
