If I select 3 points and then use the ExtractSelection filter, I would<br>
expect the IDs of the points to be 0,1,2, in the order selected.<br>
Instead, they are 2, 0, 1.<br>
<br>
Is there any way to prevent this? I am trying to set corresponding<br>
landmarks, so the order is important, and it is being lost.<br>
<br>
Thanks,<br>
