ERROR: Unknown command: reset_atoms

I’m currently attempting to reset the values of atom IDs using the “reset_atoms id” command after executing “delete_atoms.” Unfortunately, I encounter the error message: “ERROR: Unknown command: reset_atoms.” Please note that I am using the 23jun , 2022 version of LAMMPS.
variable zmax_del equal ${zmax}-2

variable zmin_del equal ${zmin}+2

region rdel block INF INF INF INF {zmin_del} {zmax_del}

group rdel region rdel

delete_atoms random fraction 0.02 no rdel NULL 482793 bond yes

#delete_atoms 命令随机删除 rdel 组中2%的原子（即约 10 个原子）。

#在使用速度命令之前，必须重置原子 ID，这通过 reset_atoms 命令完成。

reset_atoms id sort yes

velocity carbon_mid create ${T} 48455 mom yes rot yes

fix mynve all nve

compute Tmid carbon_mid temp

fix myber carbon_mid temp/berendsen {T} {T} 100 #对碳_mid 组中的原子应用 Berendsen 恒温器

fix_modify myber temp Tmid

As can be seen from the documentation, the reset_atoms command was added in LAMMPS version 22 Dec 2022.

Thank u Mr.akohlmey, Should I use command reset_ids to take place ‘reset_atoms id’

You could just update LAMMPS to a sufficiently recent version, too.

Thank u so much，I find the command ‘reset_atom_ids’ is useful in 23Jan instead of ‘reset_ids’

If you already know all of this, why did you create your post in the first place?
