wireless questions

["Mr. Epsilon" <xxe101@cs.usask.ca>]

Hello ns users,
Is there anybody who has run all the wireless tcl scripts from Marc
Greis's tutorial without any problems? I could run only
simple-wireless.tcl and wireless1.tcl. For the rest, I can get the 
.tr and .nam files, but when I run nam I get core dumped. (I have 
the daily snapshot) Also I want to know the specification for the 
.tr files. Can we get # of packets lost,tcp and ip throughput, 
retransmissions from that output file?
Thanks...
