Cadence ELC not recognising SPECTRE format

Halo, 

I am using ELC to characterise a new standard cell library. I am using a SPECTRE .scs model file, but it seems that ELC is not recognising this file format correctly, as it complains about library and section declarations which are present in the model file. I assume that my command and/or elccfg file is not set up correctly for using spectre. 

This is the contents of my command file:

db_open cell_digital
db_prepare -f
db_spice -s spectre -keep_log -keep_wave
db_output -lib cell_digital.lib -process typical -state
db_close
exit

And this is the contents of my elccfg file:

# Specify the environment variable settings.
EC_SIM_USE_LSF=1;
EC_SIM_LSF_CMD=" ";
EC_SIM_LSF_PARALLEL=10;
EC_SIM_TYPE="spectre";
EC_SIM_NAME="spectre";
EC_SPICE_SIMPLIFY=1;
EC_CHAR="ECSM-TIMING ECSM-POWER";


SUBCKT="cell_digital_SPICE_netlist.scs";
MODEL="model_file.scs";
SETUP="setup.ss";
PROCESS="typical";

Can somebody guide me into the right direction?

Thank you,
