[MUMmer-help] Adding icons to MUMmerplot output

[ADAM P. T. <apt...@st...>]

Does anyone know how to highlight the location of a sequence feature in MUMmerplot output? 

I am investigating an expanded gene family, paralogues occur on a number of different scaffolds. I have done an all against all comparison with Promer to identify syntenic regions around the duplicated genes, which was then visualised using mummerplot. 

It is difficult to tell where exactly paralogues occur in the graphic generated - So I would like to either A) add markers to the X/Y axises as a visual aide, or B) have mummerplot draw a mark where my gene occurs in self-self scaffold comparisons. 

Is it possible to achieve this by manually editing the gnu-plot script or .ps file output by MUMmerplot?

Thanks, 

Adam
