Table 4 The Q₃ accuracy comparison of SymPred using dictionaries compiled from different percentages of the template proteins.

Percentage of template pool	10%	20%	30%	40%	50%	60%	70%	80%	90%	100%
Number of template proteins	830	1660	2490	3320	4150	4980	5809	6638	7467	8297
Q₃ on DsspNr-25	70.8	73.6	75.0	76.3	77.3	78.1	78.7	79.3	79.8	80.5
Improvement	-	+2.8	+1.4	+1.3	+1.0	+0.8	+0.6	+0.6	+0.5	+0.7

The performance improves as the number of template proteins increases. SymPred’s performance improves between 0.5% and 2.8% each time the number of template proteins is increased by 10%.
