Hi all,

Anyone know how to calculate the dice similarity coefficient using 3D slicer?

You can use Segment Comparison module (in SlicerRT extension).

Hi,  
is the module name “SlicerRT” or “Segment comparison module”? I can’t find either of them.

What is the “reference segment” image and “compare segment” one?

Dear @Gonzalo_Rojas_Costa,

The reference segment is your ground truth labeling, while the compare segment is your volume segmentation

but I think both must be in .nrrd format.

Dear MOHD AKMAL MASUD  
I want to calculate the dice similarity coefficient using 3D slicer. However,  
I cannot find how to upload the test and reference segment. when I click on a reference segment and when I want to select a segmentation which has two options: rename new segmentations or delete current segmentation. I do not know what to do to find my prepared reference segment.  
I would be grateful if you guide me with this.

You have to upload in data module first.

I already uploaded my data. I clicked on the Data then chose file to add then I selected two pictures one of them is mask and another is reference.

The segmentation needs to be loaded as a “segmentation” node in Slicer, not volume. What is the file format you are using?

Hello Dear MOHD AKMAL MASUD

Sorry for reaching you at the weekends. I tried very hard and I’m quite frustrated, still I couldn’t find a problem that why I cannot calculate the dice coeffiency. Could you please connect to my computer as remote and take a look. I really appreciate it.

Best regards,  
Paria
