Hi,
Thanks for replying. I was using:
```
from numpy.lib import recfunctions as rfn
xyz = rfn.structured_to_unstructured(atoms[["x", "y", "z"]])
xyz = xyz @ transform.T
atoms[["x", "y", "z"]] = rfn.unstructured_to_structured(
xyz, dtype=atoms[["x", "y", "z"]].dtype
)
```
But I think this is cr
I'm using structured arrays to store atoms data produced by LAMMPS (I'm using a
structured array that follows its format). I need to rotate the positions:
```
import numpy as np
transform = np.array([[1, 0, 0], [0, 1, 0], [0, 0, 1]], dtype=np.float64)
dtype = np.dtype([("x", np.float64), ("y", n
