Tool Introduction & Use Cases
Correlation Plot is primarily used for calculating and visualizing correlations (between samples or genes).
Create correlation scatter plots between two genes with regression line and correlation statistics. Supports Spearman and Pearson methods. Optional density plots.
Main Use Cases:
- Assess overall consistency between samples or identify co-expression gene modules
- Provide basis for network analysis and module discovery
Key Features:
- Correlation matrix and heatmap
- Support for multiple correlation coefficients (Pearson/Spearman)
- Clustering and module visualization
Parameter Details
| Parameter | Meaning & Recommendations | Settings |
|---|---|---|
| Expression Data | 上传包含基因表达数据的文件 | Required Default: None |
| Gene for X-axis | 输入第一个基因的名称（X轴） | Required Default: None |
| Gene for Y-axis | 输入第二个基因的名称（Y轴） | Required Default: None |
| Correlation Method | Analysis Method Selection: Different methods have different distribution assumptions and robustness. Recommendation: For RNA-seq differential analysis, use DESeq2/edgeR; for microarrays, use limma; for enrichment, use hypergeometric/ORA or GSEA. | Optional Default: spearman |
| Regression Line | 是否在散点图上添加回归线 | Optional Default: true |
| Density Plot | 是否在坐标轴上显示密度分布 | Optional Default: false |
Input File Requirements
Please ensure your input file format is correct, as this is fundamental to successful analysis. Typically, you need to provide a data matrix containing gene/protein expression values.
This tool does not currently provide sample files. Please refer to the common format: typically CSV or TXT files with the first column as gene/protein IDs, followed by expression values for each sample.
Frequently Asked Questions
Q: How long does the analysis take?
A: Estimated execution time is approximately 60 seconds, depending on your data size and current server load.
Q: What if the analysis fails?
A: If the analysis fails, your credits will not be deducted. First, check if your input file format matches the sample file, or adjust parameters based on error messages. If the problem persists, please contact us through the page's feedback function.
