Hi,

I am experiencing a problem in importing mask file in NIfTI format, which is segmented using ITK SNAP, to the 3D slicer for extracting the features. I converted the extension to DICOM format, but unfortunately the problem still exist.

Please any idea on how to sort this problem out ? and thanks

If you use a recent Slicer Preview Release, then you can choose Description-\>Segmentation in the Add data dialog to load the file directly as segmentation.

In older Slicer versions, you can load the nifti file as labelmap volume (check “Show options” and check “Labelmap” to force loading the image as a labelmap image instead of a grayscale image) and then convert it to segmentation (by right-clicking on it in Data module).
