Dear Nwakamma,

Modes input file you find in the documentation section of DFTB+ on
DFTB-PLUS.INFO or explicitely at this link:

http://www.dftb-plus.info/fileadmin/DFTB-Plus/public/dftb/current/modes_in.hsd

First, you have to run DFTB+ (dftb_in.hsd) with Driver =
SecondDerivatives {} which would give you hessian.out. Then, you start
modes using modes_in.hsd as input.

For further details please consult the according manuals.

  Best regards,

  Bálint
