Hi Roger,

have a look at the descriptions of the macro language, especially the  
functions:
   http://rsb.info.nih.gov/ij/developer/macro/functions.html

You need no measurement for the center of an image:

tolerance = 0; //or whatever you like
doWand(getWidth()/2, getHeight()/2, tolerance, "8-connected")

If you don't want the geometrical center of the image, but really  
need the result of a measurement, use the getResult("Column", row)  
command.
