Grid plot of viral sequences identified with mNGS in pooled plasma samples (25 allo-HSCT patients). Each line corresponds to viral sequences assigned to one virus; the bottom line corresponds to mNGS negative (Neg1-4) and positive (Pos1/2 DNA/RNA) control samples. Each column corresponds to one pool of plasma sample (one patient). Colors represent the approximate number of reads matching virus genome detected in each pool of plasma samples. *Since they were detected in one negative control, human papillomavirus sequences were considered as likely contaminant. # cross-contamination. Abbreviations: HAstV human astrovirus, TTV torque teno virus, TTMV torque teno minivirus, TTMDV torque teno midivirus, HSV-1 herpes simplex 1 virus, EBV Epstein-Barr virus, CMV cytomegalovirus, CTRL control
