Dear Dr. @pieper and Dr. @fedorov,

**Thank you so much!**  
**It works perfectly, and moreover, I think reading multiple DSC files in the folder works fine with the code below.** (There are a few warnings, though.)

import os  
import slicer  
import MultiVolumeImporter

path1 = “/home/cndl/DSC/test/4d\_nifti/”  
path2 = “/home/cndl/DSC/test/nrrd/”  
os.mkdir(path2)  
list = os.listdir(path1)

for filename in sorted(list):  
#[success, loadedVolumeNode] = slicer.util.loadVolume(path1+filename, returnNode=True) ## for 3D NIFTI  
importer = MultiVolumeImporter.MultiVolumeImporterWidget()

mvNode = slicer.mrmlScene.CreateNodeByClass(‘vtkMRMLMultiVolumeNode’)  
slicer.mrmlScene.AddNode(mvNode)

importer.read4DNIfTI(mvNode, path1+filename)  
fn\_ext = os.path.splitext(filename)  
true\_fn\_ext = os.path.splitext(fn\_ext[0])  
slicer.util.saveNode(mvNode, path2+true\_fn\_ext[0]+“.nrrd”)

exit()

**_However, after I load these 3 NRRD files (test\_DSC, test2\_DSC, and TCGA-08-0524\_DSC.nrrd) and enter as input to DSCMRIAnalysis module in command line, it does not recognize frame identifying DICOM tag_** (error msg below). When I enter just 1 NRRD file saved with the code above as an input file, same error msg pops up. Maybe this NRRD file is not the same NRRD file that I obtained using mpReviewPreprocessor.py (the post you answer is linked [here](https://discourse.slicer.org/t/how-can-i-convert-dicom-series-to-nrrd-files-in-batch-mode/3421/9))

Could you please fix this problem?  
I always appreciate it.

All the best,  
Kyu Sung
