Dismissing errors in Netlogo behavior space

I have a Netlogo model that sometimes causes an error at setup, because just by chance, there are not enough turtles within a set radius to select X of them. When I'm at the computer I just hit setup again and keep going.

When using behavior space, what will happen when it hits one of these errors please? It seems to ignore it and move on but still record the run in the output.

I like Alan's answer. But also, if you just want the failed setup to be retried, you might consider changing your setup commands from:

setup

to something more like

let done? false
while [not done?] [
  carefully [
    setup
    set done? true
  ] [ ]
]

The documentation suggests that the experiment will be interrupted: http://ccl.northwestern.edu/netlogo/docs/behaviorspace.html

But in any case, good programming practice in any case will prevent such possible runtime errors. E.g., to try and get 2 partners in-radius 1 for each turtle:

to-report select-partners ;turtle proc
  let candidates (other turtles in-radius 1)
  if (2 < count candidates) [
    set candidates (n-of 2 candidates)
  ]
  report candidates ;may be an empty agentset!
end
