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 macro links)
