You’ll need to create a segmentation from the volume.

Import or convert the nii.gz to a labelmap node as described here:

How to convert volume to segmentation?

You can only import labelmap volumes. You have two options for having your volume interpreted as labelmap: Option A: Load your volume as a labelmap: in the Add data dialog click on Show options and check “LabelMap”. Option B: Convert your grayscale volume to labelmap in the Volumes module, Volume information section, Convert to label map row.

Then, in the Segmentations module, import the labelmap node to a Segmentation. The option should be under the “Export/import models and labelmaps” section.
