Hi,

I've been using imshow3Dfull to display a 3D matrix 192*192*17 with pixel value [0,1], it is super useful. I now need to write up a small programme to allow me extract cursor coordinate. I tried control+right click with then export cursor coordinates in 2D only. Does anyone know a way to extract 3D coordinate as [x,y,z]? Alternatively is there another viewer I can use which enables export of [x,y,x] coordinate easily? Essentially I need to write a piece of code which open the data with a 3d viewer, look into the suspicous pixel and click on it which then feed back the [x,y,z] of the cursor.

Many thanks in advance!

This is the slider callback function, when you say 'new button which gets the value property of slider' do you mean a new button in the GUI of imshow3Dfull? Sorry after reading all posts and watch videos still can't quite get my head around it! Thanks in advance!!!

% -=< Slice slider callback function >=-

function SliceSlider (hObj,event, Img)

S = round(get(hObj,'Value'));

set(get(gca,'children'),'cdata',squeeze(Img(:,:,S,:)))

caxis([Rmin Rmax])

if sno > 1

set(stxthand, 'String', sprintf('Slice# %d / %d',S, sno));

else

set(stxthand, 'String', '2D image');

end
