umgap taxa2freq
Counts ranked taxon occurrences in a stream of taxon IDs.
The umgap taxa2freq command creates a frequency table of a list of taxa on a given target rank
(species by default).
Usage
The input is given on standard input, a single taxon ID on each line. Each taxon that is more specific than the target rank is counted towards its ancestor on the target rank. Each taxon less specific than the target rank is counted towards root. The command outputs a TSV table of counts, taxon IDs and their names.
The taxonomy to be used is passed as an argument to this command. This is a preprocessed version of the NCBI taxonomy.
$ cat input.txt 9606 9606 2759 9606 9606 9606 9606 9606 9606 9606 8287 $ umgap taxa2freq taxons.tsv < input.txt 2 1 root 9 9606 Homo sapiens
With the -r option, the default species rank can be set to any named rank.
$ umgap taxa2freq -r phylum taxons.tsv < input.txt 10 7711 Chordata
