GraphML files

GraphML format, based on XML (Extensible Markup Language), allows us to describe the structural properties of graphs and interchange files between applications (see http://graphml.graphdrawing.org/).

The T-LAB function which allows us to export GraphML files is Sequence Analysis.

Four steps are all we need to do this:

1 - click on the Save Graphs button of the T-LAB function;

2 - select the graph to be exported (if required);

3 - select the nodes and the edges to be included (if required);

4 - click on GO to create the GraphML file (see below).

Two kinds of GraphML files are exported by T-LAB:
- nomefile.graphml, including only the node labels and their corresponding edges;
- nomefile.EdLab.graphml, which includes the association measures too.

Both files are ready to be edited and customized by a GraphML editor like the yEd software - produced by yWorks - which is available as a free download (see http://www.yworks.com/en/products_yed_about.htm ).

Follow two examples obtained by editing with yEd some GraphML T-LAB outputs:

1- T-LAB --> Sequence Analysis; yEd: Layout --> Organic --> Classic

2 - T-LAB --> Sequence Analysis; yEd: Layout --> Organic --> Classic; Edge Router --> Organic --> Classic
