Fig. 4From: Getting insight into the pan-genome structure with PangTreeCompatibility threshold selection using three different P values. For P=0.25 the biggest gap is between values 0.74 and 0.841 which originate from 0.3 and 0.5. For P=4 the treshold is in 0.522 which comes from value 0.85. The largest gap among original values of compatibilities (P=1) is between 0.5 and 0.72 so 0.72 is the boundary chosen as treshold in this caseBack to article page
