Area of Science:

  • Microbiology
  • Bioinformatics
  • Genomics

Background:

  • Metagenotyping is crucial for resolving microbial intraspecies diversity via single nucleotide variants.
  • Gene copy number analysis enhances understanding of microbial community metabolic functions.
  • A lack of integrated platforms hinders the analysis of metagenotyping results with relevant grouping data.

Purpose of the Study:

  • To develop an R package, stana, for processing and analyzing metagenotyping data.
  • To provide an interactive environment for exploring metagenotyping results.
  • To facilitate the study of gut microbiome metagenotypes in relation to human diseases.

Main Methods:

  • Development of the R package 'stana' with modules for preprocessing, statistical analysis, functional analysis, and visualization.
  • Creation of an interactive analysis environment.
  • Utilized over 1000 publicly available metagenome samples related to human diseases.

Main Results:

  • The stana package enables comprehensive analysis of metagenotyping data, including variant identification and gene copy number assessment.
  • An interactive environment was released, integrating over 1000 human disease-related metagenome samples.
  • Analysis of gut microbiome metagenotypes in end-stage renal disease, Crohn's disease, and Parkinson's disease was performed.

Conclusions:

  • The stana package effectively supports the analysis of metagenotyping data, confirming previous findings and generating new hypotheses.
  • The developed platform facilitates deeper insights into the link between microbial communities and human diseases.
  • The R package and interactive environment are publicly available for research use.
