When I execute the following code it runs perfectly and shows me the slices.
for i = 1:64
figure(1); imagesc(imgaussfilt3(max(img(:,:,i),0))); axis off; axis equal; colormap gray; colorbar;
title(num2str(i));
% caxis([0 0.01]);
% caxis([0.010 0.025]);
% caxis([0.5 2.5]);
pause(0.50);
end
% But I want to plot the slices on the Y axis protion Like:
for i = 1:64
figure(1); imagesc(imgaussfilt3(max(img(:,i,:),0))); axis off; axis equal; colormap gray; colorbar;
title(num2str(i));
% caxis([0 0.01]);
% caxis([0.010 0.025]);
% caxis([0.5 2.5]);
pause(0.50);
end
%% Error : I am having the following error.
Error using image
Color data must be an m-by-n-by-3 or m-by-n matrix.
Error in imagesc (line 52)
hh = image(varargin{:}, 'CDataMapping', 'scaled');
%% Can anyone help me in this issue. Thanks in advance for your kind help.

You need to reorient the data. You could use permute(), or you can do it with squeeze():
imagesc(imgaussfilt3(max(squeeze(img(:,i,:)),0)));
