[SOLVED] Duplication of nodes after importing data from csv

Postby vanetreg » 08 May 2013 13:22

Hello,

I imported a csv where nodes are URLs. URL can be either source or target.
Edge is a connection from source to target URL.
I want to identify link pyramides...
After importing I see I have several duplicated nodes of URLs, like:
anydomain.com and anydomain.com" so a " added to the URL string.
In the graph these nodes are separated nodes but they shouldn't be.

Does anyone have an idea why this is happen and how to solve the issue?
Thanks
A

Hi,

Looks like you might have imported your edges as nodes. Make sure you select "edge table" when you import your csv for edges.

If this is not the origin of your problem, please follow strictly the steps of the tutorial: http://wiki.gephi.org/index.php/Import_CSV_Data

Usually bug and mistakes are only the result of errors made during this import process.

Best,

Clement

Hi Clement,
you were right, I imported the edges as nodes.
It would have been a real help for beginners in the quoted Tutorial if it says user should import nodes csv first, then edges csv, where user should add a header row to the edge data csv with text "Source" and "Target".
Best,
A
