Sentence examples for taxa assignment from inspiring English sources

While assignment to pre-determined taxa is an operation distinct from the description of taxa, assignment accuracy is related to the ability of the character system used as the basis of assignment to track organismal phylogeny (i.e. display a phylogenetic signal [ 14]).

Since Hebert et al. [ 12] proposed that DNA barcoding could be used to assign queries to higher taxa, researchers have performed higher taxa assignments using ad hoc criteria based on the frequency of best hits, degree of sequence similarity, bootstrapping or BLAST scores (e.g. [ 18- 22]).

To address the question whether the gene families were on average in agreement with the plurality topology, we performed the following randomizations: for each gene family, taxa assignments on bootstrap trees were reshuffled.

The QIIME pipeline with standard scripts and default settings was used for taxa assignments (genus and higher), diversity estimates (OTUs, Chao1 index, phylogenetic distance index, Shannon index, and Simpson index), and phylogeny-based analyses using UniFrac [ 37, 59, 60].

The total number of taxa assigned to a unique MOTU (correct assignment rate) was also reported.

As both draft genomes as well as the catalogue of carbohydrate active enzymes in cow rumen are incomplete, in addition to our training data not covering all plant-biomass-degrading taxa, such ambiguous assignments might be better resolvable with more information in the future.

Unlike best BLAST, rank-flexible classifiers LCA and SPANNER are not guaranteed to have incorrect assignments for taxa novel at ranks higher than genus, as assignments can be made at higher ranks.

To estimate the sampling distribution of numbers of assigned taxa in synthetic reads data, the results of taxonomic assignment were bootstrapped 1000 times for each taxonomic level and employed database/assignment algorithm combination at that level.

A detailed list of soil animal taxa and their trophic assignment is given in Table S2.

Through the GUI interface, a taxonomy reference tree can be used to hierarchically collect taxa and simplify the assignment of taxa into groups, and phylogenetic trees can be visually inspected using ATV [ 18].

The processed reads are analyzed by rRNAselector and QIIME to predict taxa, followed by functional assignment by a composite protein database called InterProScan.
