Hi Paola,

  If I understand your problem ,you simply need a way to run a
Z-projection, where the first and last image are somehow dynamically set.

Here is an example:

//first slice
A = 0;    
//nslices give you the number of slices, whereas the "slice
number/position will be numbered starting at zero
B = nslices()-1;  

run("Z Project...", "start="+ A +" stop=" + B + " projection=[Average
Intensity]");

Alternatively, you could create simple dialogue box to input the values
for A and B (see the dialog box Macro example
