I generated a jittered triangulation image, thresholded it, labeled it, and used "Get Segmented IDs from labeled image". Then I tried to "measure objects" and received the following traceback:

Error whilst running Analysis>Measure objects

This approach definitely worked before, so I'm not sure what the issue is.
