Converting 4D-double image into DICOM format

Hi there, I run a simulation generates 4D-double image, I can display by using the function 'imshow4' available in this link: https://uk.mathworks.com/matlabcentral/fileexchange/47188-imshow4
my question is how to convert the 4D image into DICOM or Analyze format for further analysis.
Regards

Check if this works for your data:
%generate dummy data
X=rand(100,100,3,14);
%remap [0 1] double to the [min max] of 8 bit data (wich dicomwrite prefers)
X_uint8=uint8(X*double(uint8(inf)));
%write out
dicomwrite(X_uint8,'test.dcm')
Dicom is generally quite picky, so you may have to add dicominfo or save the data slice by slice.

Hmm. The degraded images looks to me like it is displayed as [0 1], instead of [0 255]. This points to the nature of the error: I found this page, which gives the options. I would suggest you set this parameter manually, so Matlab doesn't have to guess it (I would go for MONOCHROME1, but that is a guess).
info_struct.PhotometricInterpretation='MONOCHROME1';
dicomwrite(X_uint8,'test.dcm',info_struct)
