Can not produce layout

[rimi-299]

Hi I have followed every steps. But I am getting stuck at the last part and can not produce the layout. Can you please tell me what I am doing wrong here? Thanks!

Indeed, this is a bug! Until I have some time to fix it, you should be able to work around by explicitly setting (the default) export format:

./graph_viewer cpu 20 1 wg 5 1 approximate "out/out.ca-AstroPh" . png 1250 1250
