Table 2 Comparison to previous works—coding potential: maximal information content of each nucleotide before indexing or error correcting

Parameter	Church et al. [12]	Goldman et al. [17]	Yadzi et al.[19]	Grass et al.[18]	Bornholt et al.[24]	Blawat et al. [22]	Erlich et al. [32]	Our work (raw data)
Input data (Mbytes)	0.65	0.75	0.017	0.08	0.15	22	2.15	0.26
Coding potential (bits/nt)	1	1.58	1.57	1.78	1.58	1.6	1.98	1.6
Redundancy	1	4	1	1	1.5	1.13	1.07	1
Error correction	No	Yes	Yes	Yes	No	Yes	Yes	No

Redundancy: excess of synthesized oligos to provide robustness to dropouts. Error correction/detection: the presence of error-correction code to handle synthesis and sequencing errors. Full recovery: DNA code was recovered without any error. Net information density: input information in bits divided by the number of synthesized DNA nucleotides (excluding primers)
