Metagenomics and Metatranscriptomics Bioinformatics Analysis

With the enormous advances of metagenomic and metatranscriptomic sequencing techniques, researchers are able tostudy microbiota in a wide latitude and at a much deeper level – to identify microbes to species and even strains,to interpret a massive amount of data that can be applied to taxonomic or functional profiling in a fairly short period of time,and to link microbiota to macroscopical views such as health conditions… As metatranscriptomic analysis providesinstrumental insight into activities of genes by examining gene expression, combining metagenomic and metatranscriptomicanalysis will promise the more comprehensive understanding of microbiota to facilitate both basic interpretations and practicalapplications.

Creative Proteomics as a preeminent corporation that specializes in multi-omics and equipped with state-of-the-arttechniques and bioinformatics platforms, as well as well-experienced scientists, provides comprehensive and delicatebioinformatics services for your gut microbiota research. We offer diversified data analysis services to meet;the needs of your metagenomics and metatranscriptomics programs, which include but not limited to:

Preprocessing and quality control filteringSequence quality checking, removing adapters and low-quality bases, removing contaminations, and final quality control run.
Operational taxonomic unit (OTU) binningGrouping reads or contigs and assigning them to OTUs. Binning methods can be based on compositional features and/or alignment (similarity).
Taxonomy assignmentSearching sequences against databases of pre-assigned reference sequences for the classification practice.
Abundance table constructionConstructing OTU abundance table where each entry in the table corresponds to the number of reads observed for each sample corresponding to each OTU.
Compositional data analysis (CoDA)Providing theory and methods to deal with compositional data in a sound and principled way.
NormalizationIdentifying and removing systematic variability, a wide range of normalization methods for high-dimensional count data can be applied.
- Relative abundances computationDescribing how common or rare a species is relative to other species in a given community by calculating the total area under the curves.
- RarefactionAssessing species richness from the results of sampling, and allowing the calculation of species richnessfor a given number of individual samples, based on the construction of rarefaction curves.
Phylogenetic analysisPhylogenetic trees can be used to obtain phylogenetic distances between samples.
Diversity analysis
- Alpha diversityThe diversity within a specific sample – the average species diversity in a habitat or specific area.
- Beta diversityThe diversity between samples – the ratio between local or alpha diversity and regional diversity.
Ordination
- Principal componant analysis (PCA)To analyze a quantitative observations/variables table, correlation or covariance matrix.
- Principal coordinates analysis (PCoA)To explore and visualize a square matrix that describes the similarity or the dissimilarity of data.
- Non-metric multidimensional scaling (NMDS)An indirect gradient analysis approach that produces an ordination based on a distance or dissimilarity matrix.
Multivariate differential abundance testingTest of differences in microbial composition between two or more groups of samples.
Univariate differential abundance testingTo identify microbiome taxa associated with singular biological or clinical condition.
Data annotationComparing the individual sequence reads in databases and assigning a unique function to each read.
Microbial signaturesWhen groups of microbial taxa present in a human body habitat that are consistently predictive of host phenotype for different illnesses or treatments, these microbial signatures can be used to build models that predict therapeutic outcomes based on an individual's specific microbiota.
Biomarker discoveryBiomarker discovery that identifies organisms, genes, or pathways consistently explains the differencesbetween two or more microbial communities.
Functional interpretationInteractive exploration and analysis of the functional potential of a microbiota.
Exploratory statistical analysisProvide exploratory analysis services of human gut metagenomes and metatranscriptome.
