Re: K Sun: How to check the topology generated by gt-itm?

[Haobo Yu <haoboy@ISI.EDU>]

I don't understand. Did you ever call create-topology (or whatever that's
in r100-0.tcl to generate the topology) to actually create your topology?
If not, of course nothing'll be shown. Please please read the README of
sgb2ns to see how it's supposed to be used. Thank you.
