Surface area of MgMOF-74

[imaeda]

Dear all,
I am trying to calculate surface area of MgMOF-74 following the tutorial.
Cif file of MgMOF-74 is in RASPA2-master>structures>mofs>cif.
However, the calculation result is 0.
How can I solve this problem?
The input file is:
SimulationType                  MonteCarlo
NumberOfCycles                2000
PrintEvery                         100
PrintPropertiesEvery          100
Forcefield                          local
Framework 0
FrameworkName MgMOF-74
UnitCells 2 2 5
ExternalTemperature 298.0
HeliumVoidFraction 0.908459
SurfaceAreaProbeDistance Sigma
Component 0 MoleculeName             N2
            MoleculeDefinition       TraPPE
            SurfaceAreaProbability   1.0
            CreateNumberOfMolecules  0
