  1. Experimental groups, WGS-like libraries prepared separately using indexes 1 to 8; empty controls, indexes 33–40 and reagents used but without sample DNA; balancing library controls, samples prepared and indexed with indexes 41–48 independently and pooled with test samples after ssCir formation; all groups, total reads of all the indexes. Reads were presented after applying a Q30 > 60% filter
