Error using trainNetwork (line 165) Invalid training data. ImageDatastore not supported for regression problems.

I am trying to use dnCNNLayers. I am getting this error. I used text image [256x256], so I changed the size of dnCNNLayers. But, the problem is still there. Anyone please help me.

The ImageDatastore currently does not support for CNN regression problems.

Please give the input data via table data for specifying image files as follows.

% Define the image files as cell arrays
filename = {'C:\****\img\img1.png'; 
'C:\****\img\img2.png'; 
'C:\****\img\img3.png'; 
'C:\****\img\img4.png'}; 

% Define the target values
value = [0.1;0.7;0.3;0.5]; 

% Create a table data
tbl = table(filename, value); 

% Data Augmentation
imageAugmenter = imageDataAugmenter( ...
    'RandRotation',[-20,20], ...
    'RandXTranslation',[-3 3], ...
    'RandYTranslation',[-3 3])

augimds = augmentedImageDatastore([128,128, 3],tbl,'DataAugmentation',imageAugmenter);

% Train network for CNN regression problem
net = trainNetwork(augimds, layers, options)

Hi, This only seems to work for png or jpeg images. I would like to Read NIfTI image into an ImageDatastore for training a regression CNN. Thanks.
