copy_raw.py script usage

[KK33999]

Dear everyone,
I noticed that there is a script copy_raw.py used to replicate molecular dynamics (MD) simulation data in three-dimensional space to generate larger system data. I would like to know in what situations this script must be used.

And for example:
scenario 1 : First, I expand the cell to 661, then run AIMD, and finally use the obtained data for DP training.
scenario 2 : First, Run AIMD with a 221 cell to obtain data, then use Script copy_raw.py to expand the training set 3 times, and finally use the obtained data for DP training.

Which of these two scenarios is more recommended?

I don't think this script needs to be used.
