Hello. I have a question. Currently, I am loading more than 10 MRI series per patient, each acquired on different dates, and measuring volumes. However, the node names are inconsistent, and I would like to rename them in chronological order using the date information from DICOM files. I believe I can achieve this by accessing the Python script. Could you provide how to approach this? I’ve also searched through Python script repositories but couldn’t find a solution.

You can do something like this example:

[https://slicer.readthedocs.io/en/latest/developer\_guide/script\_repository.html#batch-processing](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#batch-processing)

Iterate through the studies for the patient and query the StudyData using the `slicer.dicomDatabase.fileValue` method to get the data to sort the data. You can load the series you want and use SetName to provide a consistent convention. You may need some special case code to deal with the variability in clinical naming conventions.

Thanks for the quick response. I have one more question. Can I perform 3D Slicer tasks using Spyder with Python? I want to use Spyder instead of the Python console.

People have done things like that - you can search for it. I didn’t find it worth the effort but if you have good luck please report back.
