Describe the bug

if global_settings[Tags.DIM_VOLUME_X_MM] < (self.probe_width_mm + global_settings[Tags.SPACING_MM]):
    self.logger.error("Volume x dimension is too small to encompass MSOT device in simulation!"
                      "Must be at least {} mm but was {} mm"
                      .format(self.probe_width_mm, global_settings[Tags.DIM_VOLUME_X_MM]))

• global_settings[Tags.SPACING_MM] is missing in the error message
