this is how I did it:<br><br> grass.run_command('g.gisenv', set="DEBUG=2")<br> p = grass.pipe_command('v.net.salesman', overwrite = True, _in='network_clean', output='salesman', nlayer=1, ccats=cats)<br>
result = []<br> for line in p.stdout:<br> result.append(line)<br> p.wait()<br> print result[-2] #this is where the node sequence sits in the debug output<br><br><div class="gmail_quote">

The last line of the output should look like this, giving you the category values of the nodes in route order:<br>
<br>
Nodes' categories (layer 2, 994 nodes):<br>
42,41,164,38,126,15,52,84,16,<u></u>55,17,157,60,6,61,8,1,76,72,<u></u>46,47,68,24,25,26,28 <br>

How could I parse the 'Nodes categories' array from the debug output (I'm stuck with 6.4.1 for now)? More specifically , I need to do it in Python with grass.script.<span class="HOEnZb"><font color="#888888"><br>
