Hello dear list,
I have some problems in 5.7, I wish you help me…
Sometimes that I use of d.what.vect, it shows me:
Buttons
Left: what’s here
Middle: toggle flash color
Right: quit
But when I click left key of the mouse on the map
nothing happens and if I do it again it shows:
Broken pipe
and quit from d.what.vect
When I am successful on use of d.what.vect, I have
these values on my street map:
…
Type: Point
field: 1
category: 6
…
…
Type: Point
field: 1
category: 160
…
Now I want to find the best path between two
points
so I use:
v.net.path input=Teh_Vect output=t2 type=line
afield=1 nfield=1
It shows:
Vector ‘t2’ already exists and will be
overwritten.
Building graph:
Registering arcs … 100%
Flattening the graph … done.
Graph was built.
Now I write :
6 160 (Is it correct?)
But nothing happens.

WARNING: 61 points without category.
6 160
WARNING: No point with category 6
WARNING: No point with category 160
Would you please tell me my wrong and explain me more
about v.net.path?
What 'nothing happens' does mean? Empty vector? You should close
stdin by Ctrl-D, and it shoud do something.
BTW, I would recommend to use different field for points, so that you can later link
arcs (lines) and nodes (points) to different tables with different structures.
