How can I convert DICOM series to NRRD files in batch mode?

Dear Dr.Fedorov,

I re-installed Slicer-4.9.0 with 2018-07-22 nightly build version, and re-installed the extension DSCMRIAnalysis (27291).
However, same as the last time, it worked with DICOM module to make dicom files of DSC into nrrd files, but mpReview Preprocessor won’t work in GUI as well as in command lines.
I think I correctly entered the directory path of mpReviewPreprocessor.py.

Could you please fix it ? or please let me know how to use DICOM modules in command line.

All the best,
Kyu Sung
