[BioC] question about RamiGO adjM2gml

[Tim [guest]]

Hi,
I used RamiGO to produce .gml file so that I can load my file to Cytoscape.

However, when I followed your sample code in the user manual,
goIDs <- c("GO:0051130","GO:0019912","GO:0005783")
color <- c("lightblue","red","yellow")
dd <- getAmigoTree(goIDs=goIDs,color=color,filename="example.gml",picType="dot",saveResult=FALSE)
tt <- readAmigoDot(object=dd)
## exportCytoGML is called inside adjM2gml
adjM2gml(adjMatrix(tt),relations(tt)$color,annot(tt)$fillcolor,annot(tt)$GO_ID,annot(tt)$description,filename="example.gml")


I found there is an error in output gml file.

In the gml file, I can find only 33 nodes, however, the in last 3 edges, there are source 34 (source node id 34).

It seems that the node index starts from 0, however, in edge, the source and target are indexed from 1.

thanks for help
Tim
