Assigning node number vtk file

Hello there,
I’m facing the following problem:
I’m making a vtk file with all my point, but I do not want to assign the default number of the node in vtk I have my numbering instead.
I’m generating a file like this:

# vtk DataFile Version 2.0 
Prova_strutturale_mesh 
ASCII 
DATASET POLYDATA 
POINTS 174 float 
0.0 0.0 0.0
0.0 0.0 0.19238977724999995
0.0 0.0 0.6124497279
0.0 0.0 1.18605117315
.
.
.

So vtk has it’s own numbering, but I know, for example, that the first node has tag 150, how to assign it?
