- use the -v command line option to get some debugging info (arbitrarily, -v5 is what I use)
- on Linux, this command will give timestamped debug info (How to timestamp (dot, fdp, neato, twopi, circo) -v output):
{ dot -v5 -T... myfile.gv >myfile.xyz ; } 2>&1 | ts -s >mystuff.log - you did not mention nslimit1 Are you using it? (this stuff is poorly documented)
- I am not an expert, just a groupie, but try this:
dot -Gnslimit=2 -Gnslimit1=2 -Gmaxiter=5000 -v5 -T... - How many nodes and edges in your graph (gc will answer this).
- Can you share your input?
