how to open .nhdr file

headerInfo = 
  struct with fields:
                   content: 'res'
                      data: []
                      type: 'double'
                 dimension: 3
                     space: 'left-posterior-superior'
                     sizes: [135 135 74]
           spacedirections: {'(3,0,0)'  '(0,3,0)'  '(0,0,3)'}
    spacedirections_matrix: [3×3 double]
                     kinds: {'domain'  'domain'  'domain'}
                    endian: 'little'
                  encoding: 'raw'
               spaceorigin: [3×1 double]
                 datafiles: {'data.raw'}

Dear @DGM, what i need is to display sizes: [135 135 74]

I tried this want using function nhdr_nrrd_write.m as attached, but got error:

                 headerInfo = nhdr_nrrd_write('res.nhdr', headerInfo, 'a.dcm');
                 %res.nhdr - my filne name
                 %a.dcm - my new file name that want to create
                 
                 

ERROR:

                 Error using assert
                 Sizes mismatch: [135 135 74 ] in headerInfo structure is not compatible with the size of the data array [0 0
                 ].
                 
                 
                 Error in nhdr_nrrd_write (line 92)

Dear @DGM,

But I got error

headerInfo = nhdr_nrrd_read('res.nhdr',true) % read the data also
Error using nhdr_nrrd_read
While reading detached header file res.nhdr:
detached data file number 1/1 (data.raw) could not be opened.
