How can I display the parametric map from multivolume analysis as a colormap?

Dear Dr Fedorov,
It worked, thank you!

May I ask you some additional questions?
(1) on the volume module, I set the output ktrans image display->lookup table->ColdToHotRainbow, and illustrate image of a certain frame and Ktrans image together, the blue dim background (as is on the pic) is bit annoying. Is there a way to clear blue background?
(2) for the ktrans map, I would like to get the exact value of each pixel (voxel), is there a way to extract the data?
I read your previous conversation with kirezgik, are those values Ktrans map, ve map values? If so, how could I extract them?

Sorry for my maybe silly questions, I am a newbie in 3DSlicer. I find this community is very nice and kind. And most of all, I am very grateful to all the contributors!!!
