Gephi does not import edgeslist correctly from csv

[rsbaptista]

Expected Behavior

When import an edgelist to build an undirected graph with sum edges option, import edges a-b and b-a as one edge with weight = 2

Current Behavior

When I have two edges a-b and b-a, Gephi is not importing both.

Possible Solution

Steps to Reproduce

1. Create a csv file like this:

Source,Target
a,b
b,a
a,c
c,a

2. Open Gephi and go to File > Open and then open the csv file

3. Select directed graph and sum the edges. Here you can see the information about nodes and edges correct.
   

4. But then, no edges imported. Only the nodes
   
   

Context

Your Environment

• Version used: Gephi 0.9.2
• Java version: 8 update 261
• Operating System: Windows 10

Thank you for this report. Did you try changing the edge merging settings?

Cannot reproduce. Do you mean undirected or directed? You use them interchangeably.

For directed, the edges in 0.10.0 are:

	Source	Target	Type	Id	Label	Weight
0	a	b	Directed	0	nan	1
1	b	a	Directed	1	nan	1
2	a	c	Directed	2	nan	1
3	c	a	Directed	3	nan	1

For undirected, the edges in 0.10.0 are:

	Source	Target	Type	Id	Label	Weight
0	a	b	Undirected	0	nan	2
1	a	c	Undirected	2	nan	2

These two seem correct for your dataset.
