Hi Huong,
I believe (but haven't tested) that the correct command line is:
catdcd -o test.xyz -otype xyz -stype pdb -s test.pdb test.dcd
The -s flag specifies the structure file (You can't just add it to the
input list). You can also use VMD to do the conversion:
mol new test.psf
mol addfile test.dcd waitfor all
animate write xyz test.xyz waitfor all
