VirStrain: a strain identification tool for RNA viruses

Table 1 The number of tie cases and the median number of best matches in all tie cases of VirStrain on 2280 ×20 simulated datasets

	75bp	100bp	150bp	250bp
5X	(903, 7)	(782, 6)	(602, 5)	(679, 5)
10X	(141, 2)	(109, 2)	(51, 2)	(65, 2)
20X	(0, 1)	(0, 1)	(0, 1)	(0, 1)
50X	(0, 1)	(0, 1)	(0, 1)	(0, 1)
100X	(0, 1)	(0, 1)	(0, 1)	(0, 1)

Each cell contains a tuple with the first number being the number of tie cases and the second number being the median number of strains in the top-ranking group. For example, “(903, 7)” in the combination 5x and 75bp means when the reads have the length 75bp and coverage 5x, 903 out of 2280 experiments return multiple strains with the same score. The median number of the returned strains is 7. For the single strain experiment, the ideal case is (0, 1), indicating that VirStrain ranks the correct strain as the top one
