Effectiveness of the filtering algorithm in Mashmap2

Id	Count of output mappings			Recall scores
	Without filter	With filter	Ratio (without/with)	Without filter (%)	With filter (%)
D1	145	82	1.77	100.0	100.0
D2	6, 541, 930	3985	1642	99.9	97.5
D3	53, 331, 538	3137	17 001	99.7	97.1
D4	152, 536, 106	4756	32 072	100.0	97.0
D5	152, 266, 777	13 834	11 007	100.0	97.5
D6	18, 604, 261	12 930	1439	99.9	99.3

Note: A large fraction of mappings were filtered out by the algorithm, while the recall scores remained largely unaffected. Last column in this table is copied from Table 3 for convenience.
