Analysis of chimeric RNA sequences containing both human and HIV sequences. Counts of the location in the HIV genome of the HIV-human junctions in filtered chimeric reads. Due to abundant sequencing artifacts (Additional file 7), reads were filtered to exclude reads where the human and HIV portions contained overlapping complementarity at the sequence junction (a sign of potential artifactual formation) and to exclude reads where the viral portion did not start at a known splice site or 5′ or 3′ border of the HIV genome
