Thanks for the reply.
1) Our data is: "/Volumes/sifnosspace/ReesWork/dki_example_data_nifti/4Drdki_0.nii"
2) DKE is installed in: "/Applications/Mac64/". There are two files in this folder:  dke and run_dke.sh
3) MCR is installed in: "/Applications/MATLAB/MATLAB_Runtime/v90"
4) dke_parameter.data file is in: "/Volumes/sifnosspace/ReesWork/dke_parameters.dat"

Here is what we got after run the command line:
sifnos:sifnosspace rpr14$ /Applications/Mac64/run_dke.sh /Applications/MATLAB/MATLAB_Runtime/v90 /Volumes/sifnosspace/ReesWork/dke_parameters.dat

4) We use the default dke_parameters.dat file and changed the path as suggested:

% paths

studydir = '/Volumes/sifnosspace/ReesWork/dki_example_data_nifti'; % root folder for data from all study subjects
subject_list = {''}; % cell array of subject sub-folders within the root folder studydir
% preprocessing parameters
preprocess_options_fn_nii='4Drdki_0.nii'; % input image format ('dicom', 'nifti' or 'bruker') (default: 'dicom')
preprocess_options.navg = 2; % number of DKI series (default: 2); each DKI series must contain a b = 0 image followed by diffusion-weighted images; all series must use identical acquisition protocols (i.e., same diffusion weightings and gradient directions)
preprocess_options.extra_b0 = 1; % whether (1) or not (0) there is an additional b = 0 series (default: 1); used when preprocess_options.format = 'dicom'
preprocess_options.coreg_flag = 1; % whether (1) or not (0) to perform 6-parameter rigid-body coregistration between diffusion-weighted images (default: 1); used when preprocess_options.format = 'dicom' or 'bruker'
preprocess_options.series_description = {'DKI1' 'DKI2' 'DKI_B0'}; % list of dicom series descriptions; used when preprocess_options.format = 'dicom'
preprocess_options.fn_nii = '4d.nii'; % four-dimensional nifti image file name; no coregistration is performed between the diffusion-weighted images; used when preprocess_options.format = 'nifti'; the first image must be the b = 0 image
% imaging diffusion weightings and directions
....................

Any suggestions?
