Hi i followed these steps from a previous post.
Load the DICOM volume using Slicer’s DICOM module. Load the nii.gz file using Add data function - and in the Add data dialog, click Show Options, scroll to the right, and make sure that LabelMap checkbox is selected.
But i am having difficulties with viewing the segmentation and editing it. Currently the segmentation is of the heart and arteries, but i want to just have the coronary arteries. How would i go about doing this.
