Hi Olujimi,
1) The export for ROIs is not correct. This is a bug and will be fixed with the maintenance release scheduled for end of this week. Please contact
support(at)definiens[dot]com if you encounter this problem again.
2) The output should be in these folders:
results\Statistics\Custom
results\Statistics\Custom\ObjectStatistics.report
If you don't find it there, maybe you can send the solution (.dax) file to
support(at)definiens[dot]com with a short description such that we can have a look at it.
Best wishes,
Kai
