Regarding Creation of several frames from quantum espresso output file

[1997sankha]

Respected Sir/Mam,
I am very new to this field of ML-based interatomic potential development. I cannot understand how several frames can be generated from a Quantum Espresso output file. It always shows 1 frame. How to run DFT dimulations using QE such that I get several number of frames.

Usually I run ab initio MD files for different structures. But again, it says you have just one frame. Pls help , I am very confused
