Yeast PPI networks used in our analysis

PPI Network	# Proteins	# Interactions	Avg node degree
ICD(Gavin+Krogan)	1628	8707	10.69
FSW(Gavin+Krogan)	1628	8688	10.67

We used four yeast PPI networks derived from the raw datasets of Gavin et al. [14] and Krogan et al. [15] and subsequent scoring using four affinity scoring schemes. The properties of these networks are shown here.
