Re: [sumo-user] Crop Network File (imported from Tiger)

[Daniel K. <d.k...@we...>]

Dear Ada,

may you tell which version you use=3F I ran your network with the current SV=
N version and it shows:

Error: The number of edges in the list mismatches the edge count.
Quitting (on error).

I suppose you built a network and then removed edges from the obtained fil=
e=3F Actually, this is not a good idea, because the generated SUMO-networks =
contain many cross-references and post-processing them is very difficult.

What you could try is to export the list of edges/nodes into XML using NET=
CONVERT:

NETCONVERT <your=5Finput> --plain-output <base=5Fname>

This should generate a file with edges (named <base=5Fname>.edg.xml) and a f=
ile with nodes <named <base=5Fname>.nod.xml). You can now remove edges/nodes=
 from these files and built the network from the so gained new input files=
.

I hope this helps,
Daniel
