Thank you Michael!
That is very similar to what I want. I just need to make minor modifications.
Sincerely,
Alex

Subject: Re: Arbitrary/random line through sections stack
Hi Aleksandr,
it is not really clear to me what you want to do.
Is it the following?
(1) Define a point in the first slice and a (different) point in the
last slice
(2) Determine the intersection points of the line between these two
slices and mark them in each image
Then it can be easily done in a macro, roughly like this:
setTool("point");
setSlice(1);
waitForUser("Select point on slice 1, then press OK");
getSelectionBounds(x1, y1, width, height);
setSlice(nSlices());
waitForUser("Select point on last slice, then press OK");
getSelectionBounds(xE, yE, width, height);
roiManager("Associate", "true");
for (i=1; i<= nSlices(); i++) {
setSlice(i);
x = x1 + (i-1)*(xE-x1)/(nSlices()-1);
y = y1 + (i-1)*(yE-y1)/(nSlices()-1);
makePoint(x, y);
run("Add Selection...");//roiManager("Add");
}
run("Select None");
Michael
