do_dssp -f traj.xtc -s topol.tpr -o ss.xpm
trjconv -s topol.tpr -f traj.xtc -o protein.pdb -pbc nojump
Took several frames, here, such as model 1000, model 3000 and model 5000, and named as 1000.pbd, 3000.pdb and 5000.pdb
intra_fit protein and (name c,n,ca)
all the way from "you are looking at the wrong files", to "pymol's definition of a beta sheet doesn't agree with dssp".
what are those files I should have looked for, and how could I find a better way to show those beta-sheet out?

I had done 10ns simulation,
by dssp, can see the beta-sheet appeared very apparently, before it's alpha-helix.
there were 5000 frames, I based on the time of the picture got from dssp, I can guess around which frames is supposed to have those beta sheets.
After I took few frames which I thought might be representive, but under pymol, show cartoon, there is none beta sheet at all. There were 5000 frames, I really do not know which one is most representive.
Or maybe some parts I understand wrong.
Thanks for any advice and if I am wrong please let me know,
We've really no idea of the detail of what you've done, so can't guess. Just about anything could be the problem - all the way from "you are looking at the wrong files", to "pymol's definition of a beta sheet doesn't agree with dssp".
If you can't report the command lines you used easily, then your method was not reproducible enough, or not recorded well enough :-)
