In view of the unpredictable portion whose actual value is smaller than its predicted value (left panel), the spike glycoproteins have the largest percentages in both unpredictable type and frequency among different coronavirus proteins. With respect to the second line of evidence, we find that the spike glycoprotein has a larger percentage of unpredictable types and frequencies whose actual values are smaller than the predicted values in Fig. 2 . Comparison with the first nine proteins in Table 2 (columns V, VI, VII and VIII in Table 2 , similar to Fig. 3) shows that the difference between actual and predicted values is statistically larger in spike glycoproteins regarding unpredictable types and is statistically smaller regarding unpredictable frequency.	./cache/cord-285865-1gsy43a0.txt	./txt/cord-285865-1gsy43a0.txt
