Good morning,

I have installed the “Quantitative reporting” extension to analyze the PET segments.

However, when I load the extension, the interface doesn’t show any field (Test area, Segmentions).

I got the following error from the console:  
ITK] WARNING: In D:\D\S\S-0-build\ITK\Modules\IO\ImageBase\include\itkImageSeriesReader.hxx, line 478  
[ITK] ImageSeriesReader (0000023188D82060): Non uniform sampling or missing slices detected, maximum nonuniformity:0.007  
Traceback (most recent call last):  
File “C:/Users/drimini/AppData/Local/slicer.org/Slicer 5.6.2/slicer.org/Extensions-32448/QuantitativeReporting/lib/Slicer-5.6/qt-scripted-modules/QuantitativeReporting.py”, line 77, in enter  
if self.measurementReportSelector.currentNode():  
AttributeError: ‘QuantitativeReportingWidget’ object has no attribute ‘measurementReportSelector’

I am using the latest version of Slicer.

Thank you for your help
