Error with dendrogram tool 10.3.1

Question

Hello,

I'm trying to use the Dendrogram tool (Spatial Analyst\Multivariate) to create a dendrogram for a signature file produced using the Iso Cluster Unsupervised Classification tool. The tool runs when I unselect Use variance in distance calculations (optional), but fails with no error message when I keep this option selected. Instead I get a pop-up that background processing has encountered a serious error and is unable to continue. Has anyone else encountered this? I was able to run the Dendrogram tool fine in 10.2.1, but now with the upgrade to 10.3.1 it fails. Signature file attached.

No, I disabled background processing and the tool has now run for over an hour with no progress.

Check the conditions associated with each type of processing in:

Will it run with background processing disabled?

I just tried it with 10.2.2 and it failed in background processing. Runs fine and immediately in the foreground!
