<P>Hello dear list, <BR>I have some problems in 5.7, I wish you help me... <BR>
<P>1. Sometimes that I use of d.what.vect, it shows me: <BR> Buttons <BR> Left: what's here <BR> Middle: toggle flash color <BR> Right: quit <BR> But when I click left key of the mouse on the map <BR> nothing happens and if I do it again it shows: <BR> Broken pipe <BR> and quit from d.what.vect <BR>
<P>2. When I am successful on use of d.what.vect, I have <BR> these values on my street map: <BR> ... <BR> Type: Point <BR> field: 1 <BR> category: 6 <BR> ... <BR> ----------------------- <BR> ... <BR> Type: Point <BR> field: 1 <BR> category: 160 <BR> ... <BR> <BR> Now I want to find the best path between two <BR>points <BR> so I use: <BR> v.net.path input=Teh_Vect output=t2 type=line <BR>afield=1 nfield=1 <BR> It shows: <BR> Vector 't2' already exists and will be <BR>overwritten.
<BR> Building graph: <BR> Registering arcs ... 100% <BR> Flattening the graph ... done. <BR> Graph was built. <BR>
<P> Now I write : <BR> 6 160 (Is it correct?) <BR> But nothing happens. </P>
<P>------------------------------------------------------</P>
<P><BR>I changed my command like this: <BR></P>
<P> v.net.path input=Teh_Vect output=t4 afield=1 nfield=2 <BR></P>
<P>Now it shows: <BR>
<P> Building graph: <BR> Registering arcs ... 100% <BR> Flattening the graph ... done. <BR> Graph was built. <BR> WARNING: 61 points without category. <BR> 6 160 <BR> WARNING: No point with category 6 <BR> WARNING: No point with category 160 <BR></P>
<P><BR>Would you please tell me my wrong and explain me more <BR>about v.net.path? <BR></P>
<P>Thanks a lot <BR>
