Organism	Reads	Coverage	Identity	Score	p value
Propionibacterium acnes HL072PA1	36,222	7.29%	96.36%	0.874	3.49e −136
Escherichia coli strain 2014C-3250	59,744	4.99%	95.16%	0.837	7.32e −47
Proteiniclasticum ruminis DSM 24773	751,538	76.57%	91.83%	0.930	0

Organism refers to the closest strain in RefSeq to the suspected contaminant, based on Mash Screen distance. Reads refers to the number of reads mapped to those genomes. Coverage refers to the amount of each genome that was covered by mapped reads. Identity refers to the average identity of the covered portions based on naive consensus from the pileups. Score and P value are results from Mash Screen
