For example, I have a group of files,  
 ![1647261723(1)](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/8/b/8ba75818022c333913b9f74164881c293a69f894.png)  
Each file has a series of DICOM images,  
 ![1647261780(1)](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/a/5/a57e4b6467426bee0fc0dbc928f9287346e3c10a.png)  
I’d like to tranfer them into NRRD format,  
Is it possible to achieve it automatically in 3D slicers?  
Thanks a lot !

Assuming the dicom data is essentially volumetric then you just need to combine these two snippets into a small script:

We have a small extension called [SlicerBatchAnonymize](https://github.com/hina-shah/SlicerBatchAnonymize) that does exactly this. It should be available in the nightly Slicer’s extension index. Hope this helps.
