Dear,
could you tell me more detailed about to extract frames  from a MD to align.
i try the follow command,but it does not work,
   trjconv -s topol.tpr -f traj.xtc -skip 10  -pbc nojump -sep.
could you tell me how to align all the frames with the first pdb file that was  
extracted from traj.xtc ?
thank you for you help!

Molecules diffuse, that's why.  Use trjconv -fit as I suggested before.
