Load MRI data and view it in the Orthoslice Viewer.

load(fullfile(toolboxdir("images"),"imdata","BrainMRILabeled","images","vol_001.mat"));
s = orthosliceViewer(vol);

filename = "animatedYZSlice.gif";

Create an array of slice numbers in the required direction. Consider the YZ direction. 

sliceNums = 1:240;

Loop through and create an image at the specified slice position.

for idx = sliceNums
    % Update X slice number to get YZ Slice
    s.SliceNumbers(1) = idx;
  
    % Use getframe to capture image
    I = getframe(hYZAxes);
    [indI,cm] = rgb2ind(I.cdata,256);
  
    % Write frame to the GIF File
    if idx == 1
        imwrite(indI,cm,filename,"gif",Loopcount=inf,DelayTime=0.05);
    else
        imwrite(indI,cm,filename,"gif",WriteMode="append",DelayTime=0.05);
