A lightly modified version of Fiji.app\plugins\Scripts\Image\Hyperstacks\Temporal-Color_Code.ijm so it stops before projection, so you keep a colored stack

---- INSTRUCTION ----

1. Open a stack (8 bit or 16 bit)
2. Run the macro
3. In the dialog choose one of the LUT for time coding.
	select frame range (default is full).
	check if you want to have color scale bar.

History

080212	created ver1 K_TimeRGBcolorcode.ijm
080213	stack slice range option added.
		time color code scale option added.

		future probable addiition: none-linear assigning of gray intensity to color intensity
		--> but this is same as doing contrast enhancement before processing.
101122  plugin'ified it
101123	fixed for cases when slices > 1 and frames == 1
