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 didn't draw borders before, but the program complains
"No clusters were found".
2) I tried the same operation with another metric that has even smaller
cluster, and the program draws the borders correctly.
3) I tried some other operations on the selected nodes (e.g. Assign
metric column to selected nodes, and Statistical report), and the
program works fine for every cluster. Only 'Create Borders Around
Clusters' doesn't work.
I uploaded my new Spec file (roi.zip) with the two metrics included
('metric1': problematic one; and 'metric2': with smaller clusters that
works fine). If you have any other idea about what can be the problem...
Thank you very much,
Mateus

The only thing I can think to try is to restart Caret and repeat your
selection of all nodes within threshold 1.0 to 50000.0. 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 borders is still acting on a previous nodes
connected to node number 33651 selection, even though this radio
button isn't selected (and the green nodes show select nodes was
pressed with All nodes within threshold selected). Restarting simply
removes any previous selections, if there is a bug lurking here.
Otherwise, my only other guess is that Caret has a minimum area for
clusters, before it will generate a border around it, and the smaller
ones fall below that threshold. I'm not aware of such a limit.
If you upload your spec file (including coord, topo, and metric), I
can see if my luck is any better than yours:

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 metric columns and the program seems to work
fine. I don't know why, for this specific metric, some clusters are
left out.
I am attaching an image of caret windows. Any suggestion is well
appreciated.
Thanks,
Mateus
