1 Supplementary Figure 1 Concept of barcoding to suppress error in sequencing. Each template DNA molecule is barcoded with a random and unique sequence (marked as red, turquoise and green). All PCR generated molecules that are generated from the same original molecule receive the same barcode. If a polymerase induced error occurs (blue cross), only a fraction of all DNA molecules with the same barcode will amplify that specific error. Conversely, a template DNA molecule with mutation will generate PCR amplicons with that particular barcode and can therefore be called a true mutant.

2 Supplementary Figure 2 Organization of SiMSen-Seq analysis data produced by Debarcer. The Debarcer output directory contains files in the main output directory (denoted Top Level ) and two subdirectories found in this location (Tables directory and Figures directory). Files described by each unshaded box in the figure can be found in their respective directories.

4 Supplementary Figure 3 Fragment analysis of single-plex library at low DNA input. Unpurified libraries were generated for a target amplicon in the CD1C gene using 10, 5 and 3 ng of high quality human genomic DNA (left side) or fragmented plasma DNA (right side) along with a no DNA control (bottom). Expected library products are indicated by the horizontal bar while all other products (<200bp) are nonspecific. Clear library PCR products can be seen in all plots except the no DNA control.

6 Supplementary Figure 4 Fragment analysis of triplex library at low DNA input. Unpurified libraries were generated for three target amplicons in the CD1C, ERBB4, and COL5A1 genes using 10, 5 and 3 ng of high quality human genomic DNA (left side) or fragmented plasma DNA (right side) along with a no DNA control (bottom). Expected library products are indicated by the horizontal bar while all other products (<200bp) are non-specific. Clear library PCR products can be seen in all plots except the no DNA control.

7 Supplementary Figure 5 Schematic representation of the first three rounds of PCR used to incorporate barcodes. Figure shows PCR products that are formed in cycles 1, 2 and 3 of the barcoding PCR step. Note that only DNA strands with both forward and reverse adapter sequences (or their complement) can act as templates in the second round of PCR. These products are indicated with thicker lines.
