[DFTB-Plus-User] Possible rounding error in charges.bin

Hi all,
I am attempting to produce a band structure for a mixed Si/P system. I
have performed the charge density calculation to obtain a converged
charges.bin file, utilising a SCC tolerance of 1E-6. According to the
resulting detailed.out file:
Nr. of electrons (up): 1922.00000000
When I ran my band structure calculation, I ran into the following error:
Starting initialization...
--------------------------------------------------------------------------------
ERROR!
-> External file of charges has a total charge: 0.19220000E+04, instead
of 0.19220000E+04
I suspect this has something to do with rounding error in the
charges.bin file. Is there a keyword that can override this? Or does
anyone have any suggestion for me to try?
I am using DFTB+ RC1.1 (that passed the autotest suite) with the matsci
parameter set.
Cheers,
Akin
