Hi Mark and others,<br>
<br>
I figured out where the error I'm getting from v.net.components is<br>
coming from. I just don't know how to fix it.<br>
The problem is that when I clean my roads network it's breaking some<br>
lines and these are kept with the same categories. So when I run<br>
v.net.components it tries to calculate the connectivity of the<br>
components based on the cat value. Since there are some repeated values<br>
for broken roads, it can't continue. So I believe I need to get new cat<br>
values for the network. Just don't know ow to do it (been away from<br>
GRASS for a while)...<br>
<br>
How can I get new cat values? And can I keep the old values in order to<br>
keep the DB link to the roads network?<br>

v.category option=add.<br>

You can create new cat values on another layer and keep the old ones on layer 1.<span class="HOEnZb"><font color="#888888"><br>
