hy,
I have a doubt regarding loading '.nii' (NIFTI) files in my CNN architecture for segmentation (I am using segnet architecture). I have attached the snapshot of the error and my code. I want to load my .nii file dataset inside imds . please suggest me any option.

You would need to provide the FileExtensions option for the pixelLabelDatastore call. You will need to provide a ReadFcn property. You will probably also need a ReadFcn property for the imageDataStore .

Here if you do not define the ReadFcn explicitly, the default function used is imread() which is not supported for .nii extension.
pxds = pixelLabelDatastore(labelDir,classNames,labelIds,'FileExtensions','.nii','ReadFcn',sampleReadFcn);
imds = imageDatastore(imageDir,'FileExtensions','.nii','ReadFcn',sampleReadFcn);
The custom ReadFcn looks something like the following
function data = sampleReadFcn(filename)
data = niftiread(filename);
end

pxds = pixelLabelDatastore(labelDir, classNames, labelIds, 'FileExtensions', '.nii', 'ReadFcn', @sampleReadFcn);
imds = imageDatastore(imageDir, 'FileExtensions', '.nii', 'ReadFcn', @sampleReadFcn);
