Cannot open file anymore when converting Nifti to DICOM

I have a script where I convert MRI nifti files to DICOM. This used to work but now I get an error when trying to create a new folder and saving the converted files into that folder:

First steps work (Part I):

%% load data

% REVISIT - adapt all text between 'apostrophes'

patientID = 'patient180'; % this is the folder with the specific patient data

patientIn = fullfile('7Tseg_Brainlab', patientID); % this is the folder where the patient folders are in

patientFolder = fullfile... % this is the whole path to the patientIn folder

('here is whole path',patientIn);

addpath(genpath(patientIn));

dicom_template = '00501_3D_TSE_0.7mm'; % this is the original dicom that is used for the new dicom header

Then with this part I get an error (Part II):

% note: the [space] before the second ' after the names is necessary,

% otherwise you will get an error

cmdNiftiToDicom = ['niftitodicom.exe -o' patientFolder '\LmSTN ' patientFolder '\7T2LRmSTN.nii.gz ' patientFolder '\00501_3D_TSE_0.7mm\00001.dcm --sagittal ' '--series-description LmSTN '];

statusNiftiToDicom = system( cmdNiftiToDicom );

cmdNiftiToDicom = ['niftitodicom.exe -o' patientFolder '\RmSTN ' patientFolder '\7T2LRmSTN.nii.gz ' patientFolder '\00501_3D_TSE_0.7mm\00001.dcm --sagittal ' '--series-description RmSTN '];

statusNiftiToDicom = system( cmdNiftiToDicom);

So what I want is 2 folders, named 'LmSTN' and 'RmSTN'. This used to work and now I get the error saying 'Cannot open file', but I do use the correct path.

Check whether the values of cmdNiftiToDicom correspond to commands that you can run outside of MATLAB.

Do you need a space after the -o in the character arrays used for command construction, so 'niftitodicom.exe -o ' (space at end) rather than 'niftitodicom.exe -o' (no space at end)?
