Bootstrapping

810
The term "bootstrap" originated in the 19th century as a metaphor for self-improvement or achieving something independently, without external assistance. This concept extends to statistical bootstrapping, a self-contained method for estimating population parameters through resampling, even though it can be computationally intensive. Developed by the American statistician Dr. Bradley Efron in 1979, bootstrapping provides a robust way to perform inference when the original sample size is...

Archaea, one of the three domains of life, exhibit remarkable diversity and adaptability, thriving in both extreme and moderate environments. Historically, most identified archaea have been classified into two major phyla: Euryarchaeota and Crenarchaeota. However, recent molecular studies have expanded this classification to include three additional phyla: Thaumarchaeota, Nanoarchaeota, and Korarchaeota, each exhibiting unique characteristics and ecological roles.Thaumarchaeota: Mesophiles...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Crenarchaeota, a prominent phylum of Archaea, is remarkable for its ability to thrive in extreme environments characterized by high temperatures and acidity. These microorganisms inhabit sulfuric hot springs, volcanic systems, and submarine hydrothermal vents, where temperatures often exceed 100°C. The unique adaptations of Crenarchaeota not only allow survival under such extreme conditions but also provide insights into the mechanisms of life in primordial Earth-like...

Hyperthermophilic archaea are a group of extremophiles thriving at temperatures above 80°C, often in hydrothermal vents and volcanic soils where conditions surpass the boiling point of water. At such temperatures, proteins, membranes, and DNA in most organisms degrade, but hyperthermophiles have evolved remarkable adaptations to maintain stability and function.Unique Cellular FeaturesHyperthermophilic membranes are composed of a monolayer of biphytanyl tetraether lipids, which resist...

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Area of Science:

  • Microbiology
  • Bioinformatics
  • Computational Biology

Background:

  • Microbiome diversity analysis is crucial for understanding microbial communities.
  • Traditional methods may not fully capture the variability within microbiome data.
  • QIIME 2 is a widely used platform for microbiome data analysis.

Purpose of the Study:

  • To introduce q2-boots, a QIIME 2 plugin for bootstrapped and rarefaction-based microbiome diversity analysis.
  • To provide users with tools to apply various alpha and beta diversity metrics to resampled feature tables.
  • To enhance the reliability and comprehensiveness of microbiome diversity assessments.

Main Methods:

  • The q2-boots plugin offers eight new actions within QIIME 2.
  • It supports thirty alpha diversity metrics and twenty-two beta diversity metrics.
  • Users can apply these metrics to bootstrapped or rarefied feature tables via pipeline or action commands.

Main Results:

  • The `qiime boots core-metrics` command resamples feature tables multiple times (n iterations).
  • Alpha and beta diversity metrics are computed on each resampled table.
  • Results are integrated into summary data artifacts compatible with downstream QIIME 2 tools.

Conclusions:

  • Integrating distance matrices from resampled tables presented a challenge, addressed by q2-boots's three novel options.
  • These integration approaches yielded highly correlated results, indicating robustness.
  • q2-boots is a free, open-source tool with available source code and documentation for ease of use and implementation.
