Single Cell RNA-Seq Analysis with OmicsLogic: Empowering Your Research

Introduction

Single cell RNA sequencing (scRNA-Seq) provides unprecedented insights into cellular heterogeneity, enabling the study of individual cell gene expression profiles. However, the complex and multifaceted analysis pipeline can be challenging for researchers. At OmicsLogic, we offer comprehensive single cell RNA-Seq analysis services using advanced tools and our T-Bioinfo platform. Our expert team ensures accurate, efficient, and insightful results at every step. Here's a detailed overview of how we can assist you in your scRNA-Seq analysis.

Types of Input Files

We support various types of input files to accommodate different scRNA-Seq technologies and formats:

1. Digital Gene Expression (DGE) files
2. 10x Genomics files, including:

Researchers can upload their data using our platform's user-friendly interface, with options for direct upload, FTP, or SVL links. This flexibility ensures seamless data handling and integration.

Key Areas of Single Cell Data Analysis

1. Preprocessing

Preprocessing is crucial for ensuring high-quality input data. This step includes:

• Quality Control: Removing low-quality cells and reads.
• Normalization: Standardizing the data to make it comparable across different cells.
• Feature Selection: Identifying highly variable genes across cells for more informative downstream analysis.
• Regression of Unwanted Variation: Regressing out unwanted sources of variation, such as cell cycle effects or technical artifacts.

Tools

We provide a suite of preprocessing tools such as LogNormalize, SCT Transformation, and RegressOut to enhance data quality and reliability. Our platform allows you to customize preprocessing parameters to fit your specific dataset requirements.

2. Dimensionality Reduction

Reducing the dimensionality of high-dimensional data simplifies its complexity, facilitating visualization and analysis. This step includes:

• Principal Component Analysis (PCA): Highlighting key features and facilitating clustering and visualization.

Tools

Our platform includes tools like PCA to reduce data dimensionality effectively, making it easier to visualize and interpret complex single cell data.

3. Integration

Batch effects can skew results in scRNA-Seq analysis. This step ensures that data from different experiments are harmonized:

• Batch Correction: Correcting for batch effects to integrate multiple datasets.
• Dataset Integration: Integrating multiple datasets to harmonize data from different sources.

Tools

We offer advanced integration tools like Harmony and Seurat Anchor Integration to seamlessly combine datasets, removing batch effects and ensuring data consistency.

4. Clustering

Clustering identifies distinct cell populations based on gene expression patterns. This step involves:

• Cluster Identification: Identifying clusters of cells with similar gene expression profiles.

Tools

Our clustering tools, such as Find Clusters, enable precise identification of cell clusters, revealing distinct cell populations in your dataset.

5. Marker Gene Identification

Identifying marker genes for each cluster is crucial for characterizing cell types. This step includes:

• Marker Identification: Identifying marker genes specific to each cluster.
• Marker Visualization: Visualizing the expression of marker genes across clusters.

Tools

We provide tools like Find All Markers and Marker Plots to help you identify and visualize marker genes, enhancing your understanding of cell-type-specific features.

6. Differential Expression Analysis

Differential expression analysis identifies genes that are differentially expressed between clusters or within a cluster. This step includes:

• Between Clusters: Identifying differentially expressed genes between clusters.
• Within Clusters: Identifying differentially expressed genes within a cluster.

Tools

Our differential expression analysis tools, such as DE between clusters and DE within clusters, provide robust statistical methods to uncover biologically meaningful changes in gene expression.

7. Visualization

Effective visualization tools are essential for interpreting complex scRNA-Seq data. This step includes:

• UMAP: Uniform Manifold Approximation and Projection for visualization.
• tSNE: t-Distributed Stochastic Neighbor Embedding for visualization.

Tools

Our platform includes visualization tools like UMAP and tSNE to help you explore the structure of your data in a reduced dimensional space, making it easier to identify patterns and clusters.

8. Cell Annotation

Annotating cell types is the final step in scRNA-Seq analysis, providing biological context to the identified clusters. This step includes:

• Manual Annotation: Annotating cell types based on known marker genes.
• Automated Annotation: Using tools for automated cell type annotation.
• Species-Specific Annotation: Annotating cell types using species-specific databases.

Tools

We offer a range of cell annotation tools, including Manual Annotation, sc-type, and Celdex for Human/Mouse, to accurately identify cell types in your dataset.

Flexible Access and Customization

Research Licenses

Researchers can obtain a research license to use our advanced T-Bioinfo platform for their analyses. This license grants access to all the tools and pipelines necessary for scRNA-Seq data analysis.

FTP File Transfers and SVL Links
