The problem is that my files are in the “.nrrd” format and I cannot open them with DICOM browser. Could I convert them from NRRD to DICOM?
You can use DICOM module’s export feature: https://www.slicer.org/wiki/Documentation/Nightly/Modules/DICOM#DICOM_export. Use the latest nightly version of Slicer.
That one doesn’t work. Create a DICOM Series works!

Try Create a DICOM Series in the nightly built version
Can you be a bit more specific? What version did you try that did not work? What did you do, what did you expect to happen, and what happened?
Nightly built 4.7.0 for Windows.
My steps: 1. Create a project, 2. Drag the nrrd file under the project, 3.
export to DICOM, 4. error meesage: 
Thanks for the feedback. The instructions did not explain that you need to add a parent subject and study to your node before you can export it. I’ve added instructions to the wiki page. Please try it and let us know if the export works if you follow these steps: https://www.slicer.org/wiki/Documentation/Nightly/Modules/DICOM#DICOM_export
It works. Thanks a lot.
But it doesn’t work on the version of MAC.
BTW, how I can change the Cost Function Convergence Factor, seen below? [image:

What is working?
What is not working on Mac?
This topic is about DICOM export. If the question is not about DICOM export then please post in a new topic. Add essential information, such as what module you are using and what you are trying to achieve.
I have been trying with no success to go through the described method and convert nrrd files from https://www.embodi3d.com/ into dicom. Notably, the field “Input volume” only shows "Rename… " and “delete current node” as options, which can’t even be selected. Does that already explain what I could be doing wrong? I’m using Slicer 4.10.2 r28257
In what part of which module? Can you post a screenshot?
Do you want to export a segmentation or a CT/MRI image?
