RE: [ns] calcdest doesn't match god

I was trying to construct scenario files with ad-hockey instead of
displaying the traces. I didn't know that nam can be used to construct
scenario files. However, the .enam files seem to be different from the
standard scenarios files. It looks more like the tcl file used to start
the ns. Is there any document to explain more on this? For example, can
we change .enam to something like the scenario file? 

Also, the cmu/ns points out that the scenario files created by ad-hockey
shall be run by calcdest to get the "god" information. Otherwise, ns
might not perform correctly. However, I run a scenario with and without
calcdest info and the results are the same. So, is the calcdest info
not necessary right now to get correct result? Or, is it just a
coincident?  

Thanks,
Venus

Vint/ns uses nam instead of ad-hockey.

In Vint/ns, nodes start with id 0 while cmu/ns starts with id 1.
