I performed remd using GROMACS 3.3.1 at four different temperatures: 270k,
400k, 540k, 660k, and produced four trajectories. I want to know whether my
simulation is ok, but I do not know how to analysis my trajectories. Though I
have demux.pl script and produced replica_index.xvg and replica_temp.xvg files,
the contents of two files are the same! I use trjcat_d to produce a continuous
trajectory,according to wiki gromacs. In fact, for a REMD simulation, I can
not judge whether the simulations is ok , and if they are ok, how to further
analyze or extract useful information from trajectories! Are you clear?
Thank you for your help!

"Analyze" really doesn't tell us what you're trying to do.

You need to tell us what you're trying to do explicitly. That means text
describing your intentions, a command line that you tried to use, the
output from it, and (potentially) why you think it wasn't what you expected.
A segmentation fault is a generic problem with referencing an illegal
memory location, and thus just about anything could cause it. If there's
no GROMACS-specific error message, though, then it's very likely to be
something you've done wrongly.
