Creating Pseudocolor Images with more than 3 channels

Pang, Zhengyu (GE Global Research)
Dear all.

How do I create a pseudo-color images with more than 3 colors. I have a
set of images with 5 channels with different bio-markers, and would like
to specify the color for each marker. For example, blue color for DAPI,
green color for cytoplamic marker, orange color for target protein.

In addition, is there any automated registration plugin or tools for the
alignment for these images? Any suggestion for registration of images is
highly appreciated.

Thanks,

Zhengyu

    1. Create a stack containing the 5 images
    2. Use Image>Color>Make Composite to create a 5 channel composite
image
    3. Press shift-z (Image>Hyperstack>Channels) to open the Channels
window
    4. Select "Color" in the Channels window
    5. Use the slider under the composite image to select the DAPI
channel
    6. Select Image>Lookup Tables>Blue
    7. Select the cytoplamic marker channel
    8. Select Image>Lookup Tables>Green
    9. Select the target protein channel
    10. Open the LUT Editor (Image>Color>Edit LUT)
    11. Create an orange LUT (drag across all 256 entries then set
red=255, green=~160, blue=0)
    12. Add LUTs to the other 2 channels
    13. Select "Composite" in the Channels window
    14. Use the B&C tool (press shift-c to open) to adjust each of the
channels
    15. Use the Channels tool to enable/disable channels

For practice, open the 5 channel File>Open Samples>Neuron image, which
was added in v1.41d.

There is the StackReg plugin at

Wayne,

Thanks for your guidance. I followed your instruction and get my
composite images right.

I plan to make a macro to batch process about 200 images. I don't like
to use the function Image>Stack>"Images to Stack"  to create my stack.
It seems to me that I have no control of channel order. For instance, I
would like to put the image ending with DAPI.tif as my first channel,
and image ending with Alexa488 as my second channel. How do I realize
this in macro language?

Thanks,

Zhengyu
