Hello,

I'm working on gain/loss gene events and for that I'm using a tool that gives as an output a gene tree in Graphviz format (dot language) like this:

digraph G {
0[label=Series];
1[label=Parallel];
2[label=Series];
3[label=v2];
4[label=v5];
5[label=v8];
6[label=Series];
7[label=v0];
8[label=v3];
9[label=v6];
10[label=v1];
11[label=v4];
12[label=v7];
0->1 ;
1->2 ;
2->3 ;
2->4 ;
2->5 ;
1->6 ;
6->7 ;
6->8 ;
6->9 ;
0->10 ;
0->11 ;
0->12 ;
}

It represents the tree as a directed graph in direction from the root to the leaves. Then it enumerates the nodes and each node has a label. The last part is the edges of the tree.

I would like to convert this output to Newick format. However I don't know much about programming so I was wondering if you can help me with this, maybe you have ideas or a custom script :)
