convert grayscale using LUT to RGB and pseudocolor images

[homedoc]

Hello to all,

We have a 3D stack of grayscale images. We would like to:
(1) Apply a LUT;
(2) Convert the resulting color display to either real RGB or real pseudocolor images; and
(3) Final goal: Display trhe result in color with variable transparency and threshold using the ImageJ 3D Viewer or perhaps another similar plug-in if one is available.

Any suggestions on how to achieve (3) will be greatly appreciated.

Thanks in advance,
Dr. Dave Tulbert
