Tool Introduction & Use Cases
Multi-time ROC Curve is primarily used for bioinformatics analysis.
Features: 1. Generate ROC curves for multiple time points in a single plot 2. Default evaluation at 1, 2, 3 years (customizable) 3. Use different colors for time points (green, blue, red) 4. Display AUC values for each time point 5. Suitable for evaluating model stability over time 6. Observe time-dependent changes in predictive performance 7. Input requires: futime (survival time), fustat (survival status), and predictor column 8. Supports CSV, TXT, XLSX formats
Main Use Cases:
- Explore data patterns and support subsequent in-depth analysis
Key Features:
- Standardized processing and result export
- Key charts and table output
- Can be used as input for subsequent analysis
Parameter Details
| Parameter | Meaning & Recommendations | Settings |
|---|---|---|
| Survival Data File | 包含futime、fustat和预测变量列的文件 | Required Default: None |
| Predictor Variable Name | Missing Value Handling: Determines how to handle missing data (removal or imputation). Recommendation: Prioritize data quality. Use simple imputation for random, low-proportion missingness; remove features with high missing rates. | Required Default: score |
| First Time Point (years) | 第一个评估时间点 | Optional Default: 1 |
| Second Time Point (years) | 第二个评估时间点 | Optional Default: 2 |
| Third Time Point (years) | 第三个评估时间点 | Optional Default: 3 |
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 90 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.
