# ktGetLCA(1)

explore hierarchical metagenomic data with zoomable pie charts

## NAME

ktGetLCA - explore hierarchical metagenomic data with zoomable pie charts

## DESCRIPTION

Description:

-

  Computes the lowest common ancestor for accessions or taxonomy IDs (as arguments or from \<stdin\>). If an input is a number, it is assumed to be a taxonomy ID; otherwise it will be considered an accession or sequence ID containing an accession in the fourth field of pipe notation (e.g. "gi\|12345\|xx\|ABC123.1\|", ignoring fasta/fastq tag markers \[\>,@\]). If using \<stdin\>, the LCA can be computed for the first fields of all input lines (default), or per input line, separated by whitespace (see **-s**).

Usage:

-

  ktGetLCA \[options\] \[acc/tax\_ID ...\] \[\< acc/taxID\_list\] \> LCA

## OPTIONS

- **-s**

  Streaming mode. Each line is expected to be a whitespace-separated list of inputs for a single lowest common ancestor computation. Taxonomy will be preloaded, allowing for faster computation after a small upfront time.
