Dear I would like to download imagej-nii and also ROI (from imageJ software) and calculate the mean and std of the voxels within adjacent 5 slices (3D volume) for 6 animals. I have created code but many errors I have,,,, cause I am so beginner to use matlab.

I do not know what is the ROI format, because it is appear as text. When I search on the ImageJ website, there is no specific format for the ROI.

% for multi animal calculation.
    Sabjects={'animal1', 'animal2', 'animal3','animal4', 'animal5,'animal6'}; 
    for i =1: size(subjects,2); 
    image = load - nii(['\MRI\..\'subjects(i)'\roi.nii']); 
    for j = 0:1 
    region = voxel (mod = = i); 
    deviation (j,i+1)= std (region,[],3); 
    end 
    end
      %%this is for one animal
    image = load-nii ("name of the file"); 
    roi = load-nii ("name of the file");
    view-nii (roi); view-nii (image);
    region1= voxels ((mod (roi ,2) == 1).* (roi > 0)); 
    region2= voxels ((mod (roi ,2) == 0).* (roi > 0)); 
    deviation = std (region ,[] ,3);
