The idea of tcptrace is to convert the packet-oriented output of
tcpdump and similar programs to a connection-oriented listing showing
details of a whole TCP connection at once.

Furthermore, I can verify the orignal poster's problem:

townhouse:~# tcptrace
must specify at least one file name
usage: tcptrace [args...]* dumpfile [more files]*
Supported Input File Formats:
        tcpdump          tcpdump -- Public domain program from LBL
        snoop            Sun Snoop -- Distributed with Solaris
        etherpeek        etherpeek -- Mac sniffer program
        netmetrix        Net Metrix -- Commercial program from HP
Version: Ostermann's tcptrace -- version 3.2.5 -- Wed Feb  5, 1997

townhouse:~# tcpdump -w foo -i ppp0

townhouse:~# tcptrace foo 
1 args remaining, starting with 'foo'
Ostermann's tcptrace -- version 3.2.5 -- Wed Feb  5, 1997

Running file 'foo'
Don't understand packet format (9)
