img_64_chest.mat

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.
