Error message "some volume not assigned"

[jianmin]

Dear all and especially Prof. Graeme,
In a rutile-TiO2 2x2x2 bulk supercell that I've recently constructed, I replaced one O atom by a H atom in order to mimic the doping of H in a replacing style. After I optimized the supercell and issued the command "bader -b weight CHGCAR -ref CHGCAR_sum" to get the Bader charges of all atoms, I recieved the following messages:

some volume not assigned
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The error "some volume not assigned" is quite noticeable. Then the Bader quit without creating the three .dat files.

How do I deal with this problem?

Regards,
Jianmin

Hm, I don't recall seeing that error before. If you can please post your CHGCAR and CHGCAR_sum, I will look into the problem.

Prof. Graeme, thanks a lot for your reply. Attached please find CHGCAR and CHGCAR_sum in the compressed file.
