Runtime and memory usage of DiscoverY and CQ

	DiscoverY: female+male mode		DiscoverY: female_only mode		Chromosome Quotient
Stage	Time	Max memory	Time	Max memory	Time	Max memory
Generating female k-mers Bloom Filter	3 h 20 m	6 Gb	3 h 20 m	6 Gb	N/A	N/A
Counting male k-mers abundance (DSK)	4 h 8 m	9 Gb	N/A	N/A	N/A	N/A
Computing proportion and coverage	9 h 2 m	307 Gb	3 h 49 m	5 Gb	N/A	N/A
Filtering of Y-contigs	5 m	< 1Gb	5 m	< 1Gb	N/A	N/A
Total	16 h 35 m	307 Gb	7 h 14 m	6 Gb	14 h 2 m	5 Gb

N/A: The CQ method is alignment-based and does not involve k-merization steps. Hence the corresponding fields of runtime and memory are left as “N/A”
