              replaced.
  
          :param specfiles: the name of an ms-run file or a list of names. If None
              all specfiles are selected.
          :param compress: bool, True to use zip file compression
          :param path: filedirectory to which the ``siic`` files are written. By
              default the parameter is set to ``None`` and the filedirectory is
              read from ``self.info[specfile]['path']``
