Gephi

Length of the edge problem

Asked by snoze

Hi All,
 In past few weeks I am extensively using gephi and would like to inform you all that I am very impressed with the gephi performance. Though still it lacks one major feature and it is related to edge length.

When I use my data in following format which gephi reads and writes correctly

A B 5
A C 4
A D 3
B D 4
D C 3
..

then the edge length is not proportional to third column which i use fruchtrman reingold algorithm.

Which same file is displayed correctly in cytoscape. If gephi can incorporate this feature then it is far better than mulimillion $$$ funded Cytoscape.

I would highly recommend GEPHI and congrats to its developers.

Hi,

The fruchtrman reingold algorithm in Gephi doesn't use the edge's weight in the calculation, that's why you obtain a different result. I created the bug 656732 for that enhancement.

A good workaround is to rather use 'Force Atlas' algorithm, which uses the weight, and by the way does a better job that fruchtrman reingold in many cases.

Can you help with this problem?
