calculate the CN after changing the type in the dump file

Dear all

I want to calculate the coordination number after changing the type of atoms in the dump file is it possible ?
because lammps can not read the ID of atoms in the dump file
any help please ?

you are not making much sense here. once LAMMPS has written the data, why and how would you want to change it? computation of properties is usually done before that.

that statement is not correct.
