[GRASSLIST:2620] v.net.path

[Maliheh]

Hello dear list, 
I have some problems in 5.7, I wish you help me... 

1. 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 

2. 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. 

------------------------------------------------------


I changed my command like this: 


 v.net.path input=Teh_Vect output=t4 afield=1 nfield=2 


Now it shows: 

 Building graph: 
 Registering arcs ... 100% 
 Flattening the graph ... done. 
 Graph was built. 
 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? 


Thanks a lot
