Thank you, but I couldn´t make it work through the way you showed me: it
makes a Z proyection  from the whole stack. What I would like to do is
to select in each image the range of slices to make the projection. So I
tried to  make this other macro that  fails to recognize A as the number
(a pop up says that it expects a numeric value for "Stop") I put in the
dialog box. Am I using the correct functions?, perhaps you can help me:

Dialog.create("Z projection stop");
Dialog.addNumber("Stop:", 30);
Dialog.show();
A = Dialog.getNumber();
run("Z Project...", "start=1 stop=+A+ projection=[Average Intensity]");

Thank you again,
Paola
