Exploring expert databases
Each Expert Database has a page similar to the miRBase page (Figure 8) where you can find what database version is currently imported into RNAcentral and explore taxonomic coverage and sequence length distribution using interactive graphs.
Sequence length distribution graph
The sequence length distribution graph can provide important insights about the data. For example, the graph below (Figure 9) shows that most sequences from miRBase are about 21 nucleotides long, which is consistent with the length of mature miRNAs. However, miRBase also provides the information about precursor miRNAs, which are more varied in length.
Tip: Explore the data by clicking on the graph to launch a search for sequences of specific length. View an example.
Species sunburst
The sunburst diagram shows what taxonomic groups the sequences are coming from (Figure 10). You can hover your mouse over the graph to explore the taxonomic distribution of species. See an example.
