**Operating system:** Windows 10
**Slicer version:** 4.13.0
**Expected behavior:** To be able to view and segment my imported DICOM files as a merged file and can go through them slice by slice.
**Actual behavior:** After importing my DICOM files, I can only see a single slice on the 4 screen viewer. I cannot drag the arrow and see several slice in series but only see one slice. If I want to see my other slices, I need to make them visible individually which means the previous view will be disabled to be looked at.
Any suggestions on how to import/merge the separated DICOM files into 3D Slicer?
Thank you.

Read the files using DICOM module as described here: [DICOM — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/user_guide/modules/dicom.html#read-dicom-files-into-the-scene)
