Ptraj can combine trajectories with the following commands:
trajin one.trj
trajin two.trj
[some operations like strip etc]
trajout three.trj
But this file will include the box size after each coord sets,
which carnal and visualization programs don't like,
Carnal expects the box. There is also the NOBOX flag
for coord sets without it.
I must admit, I could not get carnal combine trajectories as it was
suggested in the examples:
STREAM s1 a1.trj a2.trj a3.trj;
due to segmentation fault...
No bug report received.. I wonder if this is an older version.
PS: have you tried the unix merge command to combine big files or
cat file1 file2 > file3
This won't work for mdcrd because the title lines will
be embedded.
