the unit in the region command

Dear lammps users,

I have read the comments from Axel about the unit in the region command in the web page https://sourceforge.net/p/lammps/mailman/message/32486267/
my related question is that, if I use the following commands
unit real
region 1 sphere x y z radius unit box
does the coordinates of the selected atoms in the region above stand for whether the wrapped coordinates referring to the box or the real unwrapped coordinates?

Best wishes

D. Chai

Dear lammps users,

         I have read the comments from Axel about the unit in the region
command in the web page
https://sourceforge.net/p/lammps/mailman/message/32486267/
         my related question is that, if I use the following commands
                                    unit real
                                    region 1 sphere x y z radius unit box
         does the coordinates of the selected atoms in the region above
stand for whether the wrapped coordinates referring to the box or the real
unwrapped coordinates?

in LAMMPS, the "real" coordinates for 'local' atoms are always wrapped
coordinates; 'ghost' atoms can be from the neighboring domain, if the
subdomain is at the box boundary.
regions always are matched against 'local' atoms in each subdomain
only. unwrapped coordinates in LAMMPS are reconstructed after the fact
from the "real" coordinates, box lengths and image flags.

please also see LAMMPS Molecular Dynamics Simulator for more
details on how atoms are matched to regions, especially with respect
to PBC.
