Hi John,

Maybe you can use the correlate function inside FFT, here a macro how to
use it :

// open your stack
ID=getImageID();
ns=nSlices;
for(s=1;s<ns;s++){
selectImage(ID);
setSlice(s);
run("Duplicate...", "title=[s1]");
selectImage(ID);
setSlice(s+1);
run("Duplicate...", "title=[s2]");
run("FD Math...", "image1=[s1] operation=Correlate image2=[s2]
result=Result"+s+" do");
selectImage("s1");
close();
selectImage("s2");
close();
}
