Tests Identifies differentially expressed genes between exactly two experimental conditions from count tables. The workflow performs statistical testing, applies filters based on adjusted p-value and log2 fold change thresholds, and generates publication-quality visualizations including volcano plots, MA plots, and heatmaps. Takes two collections of count tables as input and produces filtered gene lists and interactive plots for interpreting expression differences. Optimal for simple two-condition experimental designs.
Inputs
| ID | Name | Description | Type |
|---|---|---|---|
| Adjusted p-value threshold | Adjusted p-value threshold | Adjusted p-value threshold to call genes as differentially expressed. If not set, default 0.05 is used. |
|
| Count files have header | Count files have header | Usually, count files generated from featureCounts tool have a header line whereas count files from RNA-STAR do not have. |
|
| Counts from changed condition | Counts from changed condition | Counts from experimental condition or changed condition. For eg. counts from treatment or knockdown samples. |
|
| Counts from reference condition | Counts from reference condition | Counts from reference condition or base condition. For eg. counts from untreated or wildtype samples. |
|
| Gene Annotaton | Gene Annotaton | The same annotation GTF used for mapping and counting |
|
| log2 fold change threshold | log2 fold change threshold | log2 fold change threshold to filter for highly regulated genes. If not set, default 1.0 is used. |
