Hi all,

I am trying to quantify SUVs in segmented areas of a mouse PET/CT study, and it results in a blank table and the following error:

 ![Slc](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/e/c/ec7f8dc357e0c6cf9dc851e23af7dc4a399731ad.png)

I have tried modifying the metadata but I could not find some of the tags with the parameter names mentioned in this error message. And I am not sure what MODULE\_INIT\_NO\_VALUE means.

Any help appreciated. Thanks
