I solved the problem.
The command that works is:
trjcat -f md00.xtc md01.xtc ... md0N.xtc -o out00.xtc out01.xtc ...
out0N.xtc -s replica_index.xvg

Is this the post you're referring to?

It's always best to refer directly to the thread you read.
What version of Gromacs are you using? I seem to recall that the quoted
error
came up in 3.3.3, but not in the 4.0.x series. I never actually solved the
above problem; my issue was with version 4.0.2, and it ended up being my own
fault for using an improper command :)
