I'd also recommend igraph.
Description below describes how I'm using igraph (cut and paste from an earlier
private email conversation).
I still use grass for some aspects of topology cleaning (eg messy OSM data),
but igraph thereafter.
This is how I'm using igraph currently...

To add my 2 cents worth, I now habitually add a default INTEGER field to my
PostGIS views to provide QGIS with a unique identifier. I label this field
‘qid’ so as not to confuse it with potentially other unique keys that may

Hi Mark,
Do you have Grass 6.4.4 or 6.4
Hi list

using the exact same steps.
Just wondering what might be different, and what the fix is?
Thanks in advance.
