Luca,
Since one of the seeds has to be on the aneurysm dome I don't think the
openopenprofiles will work for all of the seed points. In terms of updating
from the source, it takes a while for us to update since we have to work
through network administration. But do you think it would be possible to
import the vmtkPickPointSeedSelector class from vmtkcenterlines into my python
script, and would I be able to get what I'm looking for that way?
Thanks,
Ben

Hi Ben,
work has kept me from replying earlier.
Apart from the usual seeding modes, such as pickpoint and openprofiles, you can
use a couple more strategies to specify seeds from the command line, with which
you can make sure you're using the exact same points for seeds and targets.
In this case, vmtkcenterlines accepts two kinds of inputs: point ids
(-seedselector idlist) or physical coordinates (-seedselector pointlist). Point
ids are the actual id's of the surface mesh nodes. Physical coordinates are
triplets of X Y Z points.
Unfortunately, at the present stage, manually picked seeds are not piped, i.e.
you can't just go
vmtkcenterlines -seedselector pickpoint -ifile foo.vtp --pipe vmtkcenterlines
-seedselector pointlist -targetpoints @.seedpoints -seedpoints @.targetpoints
If would be a nice addition, though. Do you have the possibility of getting
vmtk from source? If so, I might add it this feature in in a short time.
Let me know
Luca

point as a target point and vice-versa in the second calculation). Is it
possible to do so?
