Details
IdentifyByRank simply identifies a sequence by a specific level of its taxonomic rank. Requires that rank information be present in the tblName, such as that created when importing sequences from a GenBank formatted file.
The input parameter level should be a non-zero integer giving the ``level'' of the taxonomic rank to choose as the identifier. Negative levels are interpreted as that being many levels from the last level in each rank.
If the specified level of rank does not exist then the closest rank is chosen. Therefore, the default level (Inf) will always select the last taxonomic level (e.g., species).
