Subject: combining trajectory file

HI Amber fans,

I am using AMBER 6 recently for my simulation work. I divided my long
simulation into several files but I have a problem in combining those files.
I tried to use "cat" to cambine them, for example:
cat md1.traj > md.traj
cat md2.traj >> md.traj

However, when I used ptraj to generate the rmsd of the new combined
trajectory files, the program did not read the file completely. Anybody who
knows to solve this problem, please tell me.

Thanks in advance.
