NodesDB file

---

Why is it needed?

• During the taxonomic annotation process, BlobTools uses a nodesDB file to infer the taxonomy at each rank for each of the hits in a hits file based on the taxID of the hit
• A nodesDB file is a "condensed" version of NCBI's nodes.dmp and names.dmp files and faster to parse.
• When the BlobTools is installed using the install script, it will automatically construct a nodesDB file.

Format

• A header indicating the number of nodes, followed by TAB-separated lines containing
• TaxID of node
• Taxonomic rank of node
• Name of node
• TaxID of parent node
