parse_taxonomy_amptk_batch: Parse multiple taxonomy strings from AMPtk.

In vmikk/metagMisc: Miscellaneous functions for metagenomic analysis

Parse multiple taxonomy strings from AMPtk.

Description

Parse multiple taxonomy strings from AMPtk.

Usage

parse_taxonomy_amptk_batch(x, withID = TRUE, multithread = FALSE)

Arguments

x	Vector of character strings from AMPtk taxonomy
withID	Logical; set to TRUE (default) if charter strings contain sequence IDs
multithread	Logical; run the function in parallel

Details

This function splits AMPtk (ex-UFITS) result of taxonomic annotation by taxonomic rank and combines it into one table. The first part of taxonomy string is assumed to be an ID of the best hit (e.g., EF040844) or a taxonomic classificator (UTAX or SINTAX) followed by a semicolon.

Value

Data frame with OTUs or species as rows and their taxonomic ranks as columns.
