Hi Donna, I replicated your probelm exactly with the roi.zip archive you uploaded. It contained only the flat coord and cut topo; have you tried using the fiducial coord with closed topo? It may not help, but it's worth a try. Yes, the problem persists. Although the clusters using

Hi Mateus, It's true the top cluster is mostly dense, but look at the node I've highlighed in red in the attached capture. I wonder whether nodes like this that cinch the cluster cause the algorithm to give up. Attached is some code I dug out of the source that might be what Caret is

Hi Donna, Thanks. I will look at the code and I let you know if I find something. Mateus Donna Dierker wrote: Hi Mateus, It's true the top cluster is mostly dense, but look at the node I've highlighed in red in the attached capture. I wonder whether nodes like this that cinch the cluster

Hi Donna, I restarted Caret and I created a new Spec file, including only the topology, flat coordinates, metric and surface shape files, and the problem persists. I did the following tests until now: 1) I tried the same operation, selecting only one of the clusters for which the program

Hi, I am trying to use 'Surface Region of Interest' to create borders around metric clusters. The nodes on the surface are correctly selected, but when I select 'Create Borders Around Clusters' only one of the clusters is surrounded by a border. I have tried the same operation with other

The only thing I can think to try is to restart Caret and repeat your selection of all nodes within threshold 1.0 to 5.0. I can see from your capture that you did this and your green nodes include clusters for which it didn't draw borders. My only guess is that perhaps somehow the create
