VG chunk help #4196

Closed tanger-code closed 5 months ago

tanger-code commented 6 months ago

Hi, I am chunking the gam file using command vg chunk -x graph.xg -a graph.gam -p path:0-50000, but it seems that I need to use -c or -S when using -p parameter. The parameter -S means: -S, --snarls FILE write given path-range(s) and all snarls fully contained in them, as alternative to -c. The parameter -c means: -c, --context-steps N expand the context of the chunk this many node steps. I really don't understand what these two parameters do,especially all snarls fully contained in them in -S.

Could you explain it further please.
