Explore microbiome data with Phyloseq. Click here to get started.

Phyloseq is an R package for the analysis of microbiome data. Microbiome data is generated from high-throughput sequencing technologies such as 16S rRNA gene sequencing or metagenomic sequencing, which allow for the identification and quantification of the microbial species present in a given sample.

Phyloseq provides a framework for importing, analyzing, and visualizing microbiome data in R. It allows users to perform a wide range of analyses, including alpha and beta diversity analyses, differential abundance testing, and network analysis. Additionally, Phyloseq integrates with other R packages for statistical analysis and data visualization.

Overall, Phyloseq provides a powerful toolset for exploring microbiome data and generating insights into the microbial communities present in a given sample.

Anlalyse RNA-seq data. Click here to get started.

Analyzing RNA-seq data involves several steps, including quality control, alignment or mapping of the reads to a reference genome or transcriptome, quantification of gene expression, normalization, differential gene expression analysis, and functional analysis of the differentially expressed genes. Here are the main steps involved in RNA-seq data analysis:

• Quality control: This step involves checking the quality of the sequencing reads using tools such as FastQC. If the quality is low, the data may need to be re-sequenced or trimmed to remove low-quality reads or adapter sequences.
• Alignment or mapping: This step involves aligning the sequencing reads to a reference genome or transcriptome using tools such as HISAT2, STAR, or Tophat. This step produces alignment files (in BAM or SAM format) that are used in the next step.
• Quantification: This step involves quantifying gene expression levels from the aligned reads using tools such as featureCounts or HTSeq. This produces a count matrix that contains the number of reads mapped to each gene.
• Normalization: This step involves normalizing the count matrix to account for differences in sequencing depth or library size between samples. Common normalization methods include TMM or FPKM.
• Differential gene expression analysis: This step involves identifying genes that are differentially expressed between two or more groups of samples. This is typically done using statistical tests such as the Wald test or the Likelihood Ratio test in packages such as DESeq2, edgeR, or limma-voom.
• Functional analysis: This step involves interpreting the differentially expressed genes by performing pathway or gene ontology analysis. This can be done using tools such as DAVID, Enrichr, or GSEA.

Overall, analyzing RNA-seq data is a complex process that involves several steps and tools. It is important to carefully QC the data, choose appropriate normalization and statistical methods, and interpret the results in the context of the biological question being studied.

Anlalyse single cell transcriptomic data. Click here to get started.

Analyzing single-cell transcriptomic data involves several steps, including quality control, data pre-processing, cell clustering, differential expression analysis, and functional analysis. Here are the main steps involved in single-cell transcriptomic data analysis:

1. Quality control: This step involves checking the quality of the sequencing reads using tools such as FastQC. If the quality is low, the data may need to be re-sequenced or filtered to remove low-quality reads or adapter sequences.
2. Data pre-processing: This step involves filtering out low-quality cells, normalizing the data, and identifying highly variable genes using tools such as Seurat or Scanpy.
3. Cell clustering: This step involves grouping cells that have similar gene expression profiles into clusters using unsupervised clustering algorithms such as k-means or hierarchical clustering. This can be done using tools such as Seurat, Scanpy, or RaceID.
4. Differential expression analysis: This step involves identifying genes that are differentially expressed between different clusters of cells. This can be done using tools such as Seurat or Scanpy.
5. Functional analysis: This step involves interpreting the differentially expressed genes by performing pathway or gene ontology analysis. This can be done using tools such as GSEA or Enrichr.
6. Data visualization: This step involves visualizing the results of the analysis using tools such as t-SNE, UMAP, or heatmaps.

Overall, analyzing single-cell transcriptomic data is a complex process that involves several steps and tools. It is important to carefully QC the data, choose appropriate normalization and statistical methods, and interpret the results in the context of the biological question being studied. Additionally, there are specialized tools and methods available for different types of single-cell transcriptomic data, such as scRNA-seq, scATAC-seq, or spatial transcriptomics, which may require different analysis pipelines.

Analyse spatial transcriptomic data. Click here to get started.

Analyzing spatial transcriptomic data involves several steps, including quality control, data pre-processing, spatial mapping, cell-type identification, differential expression analysis, and functional analysis. Here are the main steps involved in spatial transcriptomic data analysis:

1. Quality control: This step involves checking the quality of the sequencing reads using tools such as FastQC. If the quality is low, the data may need to be re-sequenced or filtered to remove low-quality reads or adapter sequences.
2. Data pre-processing: This step involves filtering out low-quality cells, normalizing the data, and identifying highly variable genes using tools such as ST Pipeline or STARmap.
3. Spatial mapping: This step involves mapping the transcriptomic data to the spatial coordinates of the tissue sections using tools such as ST Pipeline or STARmap. This produces a spatial expression matrix that contains the expression levels of each gene in each spatial location.
4. Cell-type identification: This step involves identifying the cell types that are present in each spatial location using tools such as CellFinder or SpatialDE.
5. Differential expression analysis: This step involves identifying genes that are differentially expressed between different spatial locations or cell types. This can be done using tools such as ST Pipeline or SpatialDE.
6. Functional analysis: This step involves interpreting the differentially expressed genes by performing pathway or gene ontology analysis. This can be done using tools such as GSEA or Enrichr.
7. Data visualization: This step involves visualizing the results of the analysis using tools such as heatmaps, spatial plots, or 3D visualizations.

Overall, analyzing spatial transcriptomic data is a complex process that involves several steps and tools. It is important to carefully QC the data, choose appropriate normalization and statistical methods, and interpret the results in the context of the biological question being studied. Additionally, there are specialized tools and methods available for different types of spatial transcriptomic data, such as MERFISH or CODEX, which may require different analysis pipelines.
