Yes, but the values I see in the ImageJ window are the RGB codes for each
cell of the grid, not the real numerical values of my image pixels (I use
16 and 32 bits images). I would need to translate that value to my image
values (typically from 0.3 to 10-20). My goal is to stretch quickly a lut
to a desired range to identify the hotspots where values changes are
initiated (I use stacks of fura-2 loaded cells, so that upon stimulation I
get value increases). For example, if I have min/max pixel values equal to
0.25/6.89 in my stack I usually need a lut spanning from 0.2 to 2 or 3, so
that the places where the values increase initially are easily visualized.
