09 Traverse
The Traverse tab allows you to follow a single feature across multiple levels of the QFeatures hierarchy — from precursors up through peptides, protein groups, and taxonomic aggregations. This is useful for understanding how a specific protein or taxonomic group is represented at each level of the data.
- Feature name: Enter the identifier of the feature you want to investigate (e.g., a protein group ID or species name)
- Assay: Select which assay the feature belongs to
-
X-axis variable: Choose a sample-level variable (
colData) to use as the X-axis in intensity plots
An interactive diagram showing the hierarchical relationships between the selected feature and its associated entries at other assay levels (e.g., which peptides and precursors map to this protein group).
A static ggplot showing the intensity of the selected feature across samples, with the chosen colData variable on the X-axis. This makes it easy to visualize how a specific feature varies across your experimental groups.
A summary table showing the dimensions and structure of the selected feature across all relevant assays — useful for understanding how much data backs the selected feature at each level.
