Hi, my intention is to measure the intenisty of each individual pixel without ha
ving to select each individual pixel by hand. i.e as if each pixel were a sepera
te element in a matrix, I want to know the value of each individual element in t
he matrix.
I hope this explains my problem more,
Thanks,
Richard

Not sure of the real question being asked, but placing the cursor over a
pixel will read out the values in the ImageJ mssg field. If the intent was
to
list all the pixel intensities, it seems that "save as/ text image "
option is
the fastest route vs the 1-pixel region of interests (ROI)
approach below.
Selecting a ROI and using MEASURE is more common (built-in
statistics vs
spreadsheets). Listing values within ROI can be done with
macros (see ImageJ ma
cro links)
