Reset_ids Not Working

Dear Lammps Users

For creating a hole in the diamond matrix, I deleted a cylindrical region from the matrix. After that I had to add a CNT in the hole. So, after adding when I added the command “reset_ids” in my code. I am getting this error-

Unknown command: reset_ids (…/input.cpp:246)

Can anyone tell the reason for this?

Thanking you
