I used DICOM to NIFTI converter

Is it https://www.mathworks.com/matlabcentral/fileexchange/42997-dicom-to-nifti-converter--nifti-tool-and-viewer that you used? Or was it https://www.mathworks.com/matlabcentral/fileexchange/22508-siemens-dicom-sort-and-convert-to-nifti ?

I see it was not https://www.mathworks.com/matlabcentral/fileexchange/41874-dicom-to-nifti-converter as that creates one .nii and some .txt files.

No. see the converter. Thanks
