list

Usage

list taxon tree of given taxids

Usage:
  taxonkit list [flags]

Flags:
      --ids string      taxid(s), multiple values should be separated by comma
      --indent string   indent (default "  ")
      --json            output in JSON format. you can save the result in file with suffix ".json" and open with modern text editor
      --show-name       output scientific name
      --show-rank       output rank

Examples

  1. Default usage

    $ taxonkit list --ids 9605,239934

    Performance: Time and memory usage for whole taxon tree:

    $ # emptying the buffers cache
$ su -c "free && sync && echo 3 > /proc/sys/vm/drop_caches && free"

$ memusg -t taxonkit list --ids 1 --indent "" > t0.txt
elapsed time: 3.093s
peak rss: 82.79 MB

  3. Adding names

    $ taxonkit list --show-rank --show-name --ids 9605,239934

reformat

Usage

reformat lineage

Output format can be formated by flag --format, available placeholders:

    {k}: superkingdom
    {p}: phylum
    {c}: class
    {o}: order
    {f}: family
    {g}: genus
    {s}: species
    {S}: subspecies

Output format can contains some escape charactors like "\t".

This command appends reformated lineage to the input line.
The corresponding taxids of reformated lineage can be provided as another
column by flag "-t/--show-lineage-taxids".

Usage:
  taxonkit reformat [flags]

Flags:
  -d, --delimiter string               field delimiter in input lineage (default ";")
  -F, --fill-miss-rank                 estimate and fill missing rank with original lineage information (recommended)
  -f, --format string                  output format, placeholders of rank are needed (default "{k};{p};{c};{o};{f};{g};{s}")
  -h, --help                           help for reformat
  -i, --lineage-field int              field index of lineage. data should be tab-separated (default 2)
  -r, --miss-rank-repl string          replacement string for missing rank, if given "", "unclassified xxx xxx" will used, where "unclassified " is settable by flag -p/--miss-rank-repl-prefix
  -p, --miss-rank-repl-prefix string   prefix for estimated taxon level (default "unclassified ")
  -R, --miss-taxid-repl string         replacement string for missing taxid
  -t, --show-lineage-taxids            show corresponding taxids of reformated lineage

Examples:

2. create and edit ~/.bash_completion file if you don't have it.

        nano ~/.bash_completion

   add the following:

        for bcfile in ~/.bash_completion.d/* ; do
          . $bcfile
        done

Usage:
  taxonkit genautocomplete [flags]

Flags:
      --file string   autocompletion file (default "/home/shenwei/.bash_completion.d/taxonkit.sh")
  -h, --help          help for genautocomplete
      --type string   autocompletion type (currently only bash supported) (default "bash")
