I am iterating frame by frame between two different volumes of images, I want to make a video so that there is a side by side comparison. This is what I have to create the plots, now I want to save it into one video.

for i = range
    figure(fref)
    imagesc(squeeze(log(abs(vol1(i,:,:)))), [0 6]);
    colormap(gray);
    title(sprintf('frame %i, ogvol %i', i, volname));
    figure(ftar)
    imagesc(squeeze(log(abs(vol2(i,:,:)))), [0 6]);
    colormap(gray);
    title(sprintf('frame %i, changedvol %i', i, volname));
    if i == 150
        pause;
    else
        pause(0.1);
    end
end

Hi,

Make use of subplot() to get side by side comparison, as illustrated in the code below.

h = figure;
subplot(2,1,2);
plot(1:10);
subplot(2,1,1);
plot(5:15);
F = getframe(h);
v = VideoWriter('myFile.avi');
open(v);
writeVideo(v,F.cdata)
close(v);
