Hello,

I am a new user to VMD and NAMD so this maybe obvious.

I have a question about CatDCD. I used catdcd with the stride 100 command
to join three dcd files together. Before using the catdcd command there was
a total of 7998 frames. After I used catdcd there was 80 frames. Using VMD,
I went to the 60th frame and wrote out the pdb file for this frame.

Later I decided to used catdcd on these same three dcd files but with stride
1000 instead. This produced 8 frames. Again, using VMD I went to the 6th
frame and wrote the pdb for this frame. I assumed that these two pdb files
would be identical. They weren't.

Is there something I missed or did incorrectly?

Thank you for you time.
