Load New Graph

[Yijun Ding]

How do I load a GDF file in an none-empty graph? How do I clean all
nodes and load a new GDF file?

I got exception: java.sql.SQLException

removeComplete(g.nodes) will remove data. But some of the user fields
maybe there. How to remove a field?

Even with exactly fields, I think GUESS has problem. If I start with
an empty GUESS, then makeFromGDF (or use menu item) to load a large
GDF file, I will get exception. The file load OK on command line:

It seems that I found the problem. The GDF file with duplicated edges
will load fine in GUESS start. But it will not load with empty GUESS
from menu.

Thanks!
