    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
 
    -no-id-update <boolean> (property: dontUpdateID)
    If enabled, suppresses updating the ID of adams.data.id.IDHandler data containers.
    default: false
 
    -padding <ZERO> (property: paddingType)
    The padding type to use.
    default: ZERO
 
    -inverse <boolean> (property: inverseTransform)
    If true, then the inverse transform is performed.
    default: false
 
    -real <boolean> (property: real)
    If enabled, the real part of the tranformation is returned.
    default: true
