Table 4.
Position | dbSNP entry | Scheme | Q-values | Allele quality | Decision | |||
---|---|---|---|---|---|---|---|---|
43150343 | C/T | lossy-8 | 41G | 27G | 22G | 32G | 10.2 | G |

46014280 | A/G | lossy-8 | 27C | 37C | 37C | 10.1 | C | |
lossless | 27C | 36C | 36C | 9.9 | — |
In both cases, the lossy quality values result in a score that marginally exceeds the threshold of 10 used to call the allele. Thus, CASAVA would make a SNP call only in the lossy scheme of both cases.
