Dear all,

I am trying to do TDDFT calculations. I followed the manual to prepare the input file,when I execute the program, I get the following error:
Failure to open external file of charge data.

I attached the input file

Geometry = GenFormat {
  <<< geo.gen
}

Hamiltonian = DFTB {
  Scc = Yes
  SccTolerance = 1e-3
  MaxSCCIterations = 10000
  ReadInitialCharges = Yes
  Mixer = Broyden {
    MixingParameter = 0.1
    CachedIterations = -1
    InverseJacobiWeight = 1e-3
    MinimalWeight = 1
    MaximalWeight = 10000
    WeightFactor = 1e-2
  }
  SlaterKosterFiles = Type2FileNames {
    Prefix = "/home/bin/dftb+/pbc-0-3/"
    Separator = "-"
    Suffix = ".skf"
    LowerCaseTypeName = No
  }
  MaxAngularMomentum = {
    C = "p"
    H = "s"
  }
  Filling = Fermi {
    Temperature [Kelvin] = 300
    IndependentKFilling = No
  }
  KPointsAndWeights {
    0.0  0.0  0.0   1.0
  }
  SpinPolarisation = {}
  ElectricField = {}
}
Driver = {}
#  TDDFTB
ExcitedState = Casida {
  NrOfExcitations = 10
  StateOfInterest = 2
  Symmetry = Singlet
  WriteTransitions = Yes
  WriteSPTransitions = Yes
  EnergyWindow = 0.00
  OscillatorWindow = 0.00
#  WriteMulliken = Yes       # available for StateOfInterest non zero
#  WriteCoefficients = Yes   # available for StateOfInterest non zero
#  WriteEigenvectors = Yes   # available for StateOfInterest non zero
  WriteXplusY = Yes
  WriteTransitionDipole = Yes
  WriteStatusArnoldi = Yes
  TestArnoldi = Yes
}
#
Analysis = {
  WriteEigenvectors = Yes
  MullikenAnalysis = Yes
  ProjectStates = {}
  WriteBandOut = Yes
}

Options = {
  WriteAutotestTag = Yes
  WriteDetailedOut = Yes
  RestartFrequency = 20
  RandomSeed = 0
}

ParserOptions = {
  ParserVersion = 5
  WriteHSDInput = Yes
}

Any suggestions?

Best Regards
