Good day,
actually I don't really understand what you like to obtain.
The live-mode gives you a temporal view of the line profile, when the
stack is animated.
If you like to get all profile plots in parallel, i.e. not as a temporal
sequence, you need to write a little macro that gives you as many
profile plots as you have slices in your stack.
What do you mean by "the line is 10 pixels"?
10 pixels long or wide?
"matrix in one file"
Does that mean you don't want plots but the gray values along the
selection line?
If the latter is what you want, then here is an ImageJ-macro that shows
how to do that. (It uses a demo stack of 27 slices.)
///////////////////////////////////////////////////////
x=96; // selection x-start
y=100; // selection y-position
len=50; // selection length
run("MRI Stack (528K)"); // demo image
setBatchMode(true);
img=getImageID();
makeRectangle(x, y, len, 1);
n=nSlices;
newImage("Result", "8-bit black", len, n, 1);
rslt=getImageID();
for ( i=0; i<n; i++ ) {
selectImage(img);
setSlice(i+1);
run("Copy");
selectImage(rslt);
makeRectangle(0, i, len, 1);
run("Paste");
}
run("Select None");
selectImage(img);
setSlice(1);
selectImage(rslt);
setBatchMode(false);
run("Set... ", "zoom=1600 x=25 y=0 width=50 height=1");
exit();
///////////////////////////////////////////////////////
Paste the above macro code to an empty macro window (Plugins >> New >>
Macro) and run it.
(You need an open internet connection to load the demo stack.)
