Dear Modeller,

I was trying to do modelling with hetatm .it stopped after running a while can anyone help me where was the mistake.

## the top file is

INCLUDE # Include the predefined TOP routines SET ALNFILE = 'align.pir' , KNOWNS= '1a57', SEQUENCE = 'seq' SET MODEL_TOPOLOGY = 1, HYDROGEN_IO = on, HETATM_IO = on, WATER_IO = on SET TOPOLOGY_LIBRARY = $(LIBS_LIB6V2)/top.lib SET PARAMETERS_LIBRARY = $(LIBS_LIB6v2)/par.lib CALL ROUTINE = 'model' # do homology modelli

----------------- the log file --------------------- 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 = $(LIBS_LIB6V2)/TOP.LIB assgn___525E> Error in TOP variable assignment. assgn___544E> Variable name not recognized: PARAMETERS_LIBRARY Command line: SET PARAMETERS_LIBRARY = $(LIBS_LIB6V2)/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
