> Hi,

> I would like to program matlab code for the following situation:
>
> I want to create a set of png images, based on Analyze image
> of my choice (which will be an MRI) and an overlaid Analyze
> image (with SPM results for instance, or other data). These
> png images will be created by looping over a chosen axis (x,
> y or z) and skipping two frames each time. This way i can
> make a lightbox-like display without showing every single slice.
>
> The problem i have, is that i don't know how to overlay an
> image on top of another, making the original image
> black&white (the MR) and the overlay yellow-red and
> green-blue in case of positive or negative values. This is
> partly accomplished in the spm display functionality, but
> that code is a tad complex, and i believe i only need a few
> instructions.
>
> I can do all the other steps of reading images and asking
> input and saving a figure window to a png, just not the
> actual displaying of the images.
>
> I have matlab 6.5 with the image processing toolbox v3.2, but
> can obtain 7.0 too.
