Why MODERLLER6v2 cannot recognize these Variables?

[Lesheng Kong <>]

Hi,
When do modeling, I got the following error message:
assgn___544E> Variable name not recognized:  MODEL_TOPOLOGY
              Command line:  SET MODEL_TOPOLOGY = 1, HYDROGEN_IO = ON, HETATM_IO =ON, WATER_IO = ON
assgn___525E> Error in TOP variable assignment.
assgn___544E> Variable name not recognized:  TOPOLOGY_LIBRARY
              Command line:  SET TOPOLOGY_LIBRARY = $(LIB)/TOP.LIB
assgn___525E> Error in TOP variable assignment.
assgn___544E> Variable name not recognized:  PARAMETERS_LIBRARY
              Command line:  SET PARAMETERS_LIBRARY = $(LIB)/PAR.LIB
assgn___525E> Error in TOP variable assignment.
compile_563E> Please correct the errors reported above and rerun MODELLER.
recover____E> ERROR_STATUS >= STOP_ON_ERROR:        1       1


But I follow FAQ 15, why MODERLLER6v2 cannot recognize these Variables?
Is it possible that my installation has problems?
Thank you very much!

My model.top:

SET ALNFILE = '1TCH-1TCG.ali'
SET KNOWNS = '1TCH'
SET SEQUENCE = '1TCG'
SET ATOM_FILES_DIRECTORY = './:../atom_files'
SET STARTING_MODEL = 1
SET ENDING_MODEL = 5
SET MODEL_TOPOLOGY = 1, HYDROGEN_IO = ON, HETATM_IO=ON, WATER_IO = ON
SET TOPOLOGY_LIBRARY = $(LIB)/top.lib
SET PARAMETERS_LIBRARY = $(LIB)/par.lib
CALL ROUTINE = 'model'
