Table 2 Gene mapping groups with different sequence correspondence complexity
Group | Microarray probes/probe sets | RNA-Seq genes | Concordance |
|---|---|---|---|
A | Each probe set can be exclusive mapped to one RNA-Seq gene. It is identical to RNA-Seq A set | Each gene can be exclusively mapped to one array probe set. It is identical to array A set | High |
B | Each probe set can be mapped to one RNA-Seq gene, but the gene can be mapped to multiple array probe sets. It is a subset RNA-Seq C set | Each gene can be mapped to one array probe set, but the probe set can mapped to multiple genes. It is a subset of array C set | Low |
C | Each probe set can be mapped to multiple RNA-Seq genes | Each gene can be mapped to multiple array probe sets | Lowest |
D | Probe sets cannot be mapped (unique probe set) | Genes cannot be mapped (unique genes) | Unique features |
