Here, we indicate whether the phenotype predicted by our model, or seen in experimental data is arrhythmic (AR) or shows a change in period in hours. Experimental data can be found in Liu et al (2007), except those marked with * which can be found in Ko et al (2010). See Materials and methods for details.
