Gephi 0.7beta released

Major milestone for Gephi today. The 0.7 beta version is ready for download for Windows, Mac OS and Linux platforms. It brings many awaited features and more than 80 bug fixes!. Stability and productivity improvements are the main objectives of this release. A complete support for longitudinal network is part of this release, it is now more easy and flexible to import and explore dynamic networks. Consult this new tutorial to see how input longitudinal networks in Gephi. We support three different methods, to cover all use cases.

Because it’s a major release, changes are not deployed through the AutoUpdate, you need to download and install the new version if you had the alpha. Plug-ins also need to be checked for compatibility. They will reappear on the Plugin Center in the coming days, as they are verified.

Consult the release notes and the new Javadoc for more informations.

An announcement for modules developed this summer by the Google Summer of Code students, in particular Neo4j and Social Network import. They may be fully integrated in Gephi for its 0.8 version, in the meantime they will be released as plug-ins through our Plugin Center. Stay tuned, it will be fast.

A new version of the Gephi Toolkit will be released in a few days, based on the beta codebase.

Features highlight

New Data Laboratory

The Data Laboratory receives tons of new features, developed this summer by Eduardo Ramos. It now proposes to manipulate and edit data in a broader and more productive way. A detailed list of features is available on the Introducing Data Laboratory post. The laboratory is also now auto-refreshing when filters are manipulated. Another essential point is that the laboratory is easily extensible with plug-ins.

Longitudinal networks

They are now fully supported in Gephi. Explore how the network topology change over time by using the Timeline component, which now appears automatically. The major improvement is the dynamic attributes support. The edge weight or any attribute value can evolve over time as well, and the visualization shows the value in the right range. Enable the timeline with a single button. See tutorial.


Simple edit by selecting one or several nodes or edges in the Data Laboratory. Keep Control key on the table to select several rows and change values of several elements in one action. Edit also manually visualization variables like color, size or position. The Edit window is available by right-clicking on rows. Many other features are now available through the context menu, and more can be added with plug-ins.


General Data Laboratory actions like Add node/edge, Search/Replace or Import CSV. The Search/Replace feature shows an advanced UI to search and replace values in the table cells. It can do a normal search or a regular expression based search, among other useful options. It is implemented in a separate controller that is part of the Data Laboratory API.

Columns merge

Manipulate columns and do basic calculations. On numerical columns one can get sum, average, median, … from several other columns. New columns can be created from a regular expression based on a existing column. Among other merge strategies, a Time Interval column can be get from a simple numerical column. Get a longitudinal network from a simple ‘year’ column in your data.

Label visibility

Decide whether a label should be visible or not from the filter result. Nodes and edges not in the filtered graph will have their labels hidden. Can be reset by the ‘Reset Visible’ action (left of graph window).

Copy and Move to a workspace

New option when right-clicking on the graph. You can copy or move the selection to a new or existing workspace.

Import ‘Missing Nodes’ option

New option in the import panel to import nodes which were not properly defined in the file. Use this option to create nodes only from their reference in edges.

Import Time Frame

Their are different way to import longitudinal network in Gephi. One of them is to import multiple ‘static’ files, where each is a particular snaphsot in time (one file per day or per month). There is a new option for that in the import report. See this tutorial section to use it.

Time Frame settings

Decides whether the time format is a date or a real number. The processor will look for existing elements in the workspace and append the time frame to nodes and edges. The network becomes longitudinal, each node, edge and attribute is defined with time intervals.

Preview Presets

The Preview settings has now default presets: Default Curved, Highlight Mutual Edges, Small Labels and more.

Rescale weight in Preview

New option in preview to have edge weight look the same as Overview. Meta-edges have also now a separate scale slider in Visualization settings. This scale value is used in Preview to respect dimensions.

Original color option

When edges color are imported from a file or set by Partition, they have a custom color. This color mode can now be rendered by Preview by setting ‘Original’ in the color dialog.


Localization is now possible in Gephi, French and Spanish versions will be available soon. Please consider helping us, show up on the Translations forum section.
