Using Edge Weights in Layout

[DataJunkie]

I have a column called "jaccard" which is, you guessed it, the Jaccard similarity between the two nodes connected by a particular edge.

In my formulation, higher Jaccard means more similarity (as opposed to Jaccard distance which is the opposite).

I would like to use this column when building the graph, but I am not sure how. Also, how can I tell Gephi that when laying out the graph, higher weight means the nodes should be closer together (rather than the opposite)?

Thanks,
Ryan

Hi,

By default higher weight means closer nodes for the layouts which take edge weight into account.

You should duplicate your column to the "Weight" column.

Perfect! That gets me to my next question

How do I copy the contents of the Jaccard column into the Weight column?

I have tried using the GUI but:
- the current Weight column is for some reason, all 1s.
- I cannot delete the Weight column.
- I cannot duplicate the Jaccard column and rename it to Weight since I cannot delete the existing Weight column.
- I cannot use the "copy column" option in the GUI because it does not let me choose a source column (it is always set to Weight)

Any advice?

Thanks again,
Ryan

Huh, can you do it on Excel?

I think that's my only option .

When I get some time, I'd like to work on making the Data Laboratory GUI more useful. Of course, I have to prove myself to become a patcher or committer first

Hi,
You can use the "Copy data to other column" feature to fill Weight column with your other column's data.
