I'm trying to examine the DAG unifying my GO lists but there seems to be a problem converting the DOT files into trees for large numbers of GO terms (>15). I've included the code below.

Can anything be done to make readAmigoDot process up to 100 go terms? Is there another tool I can use to convert the DOT into an igraph useable format?

> tt <- readAmigoDot(getAmigoTree(goIDs=go[1:10], picType="dot", saveResult=F))
> tt <- readAmigoDot(getAmigoTree(goIDs=go[1:15], picType="dot", saveResult=F))
> tt <- readAmigoDot(getAmigoTree(goIDs=go[1:18], picType="dot", saveResult=F))
Error in `[<-`(`*tmp*`, relations[i, "parent"], relations[i, "child"],  : 
  subscript out of bounds
> tt <- readAmigoDot(getAmigoTree(goIDs=go[1:20], picType="dot", saveResult=F))
Error in `[<-`(`*tmp*`, relations[i, "parent"], relations[i, "child"],  : 
  subscript out of bounds

> dotRes <- getAmigoTree(goIDs=go[1:20], picType="dot", saveResult=F)
> tt <- readAmigoDot(object=dotRes)
Error in `[<-`(`*tmp*`, relations[i, "parent"], relations[i, "child"],  :
