Model outputs along time for: a the original model (solid lines) and the reduced model (dashed lines); b the original model (solid lines) and the coupled sub-models without propagation errors (dashed lines); c the coupled sub-models, with (dashed lines) and without (solid lines) propagation errors. d The equations for the total concentration of protein PER (P Tot ), CRY (C Tot ) and BMAL1 (B Tot ) are: P Tot =P C +P CP +PC C +PC N +PC CP +PC NP +I N , C Tot =C C +C CP +PC C +PC N +PC CP +PC NP +I N , B Tot =B C +B CP +B N +B NP +I N
