Loading Data

The Data Selection panel controls what becomes available in BRIDGE.

Main controls:

1. Select species.
2. Select data table.
3. Select datapoint columns.
4. Select annotation table.
5. Click Load Data.
6. Optionally remove loaded tables.

How BRIDGE uses your selections:

• It reads table and annotation metadata from SQLite.
• It queries selected columns from the chosen data table.
• It computes or loads cached processed output.
• It enables module tabs for the loaded dataset.

Loaded datasets:

• are listed in the sidebar
• can coexist in one session
• can be removed from the session without deleting from the database

Common issues:

• No tables appear: check table naming, species prefix, and table_metadata.
• No annotation appears: check annotation_metadata.
• Load succeeds but plots are empty: validate identifiers and selected datapoints.

First successful load checklist:

• The selected species matches the table-name prefix.
• A data table is visible in the table selector.
• Datapoint columns are selected in the intended biological order.
• A matching annotation table is selected.
• The loaded dataset appears in the session after clicking Load Data.
• PCA or Raw Heatmap can compute a first plot.

Practical tip:

• Start with one table and a small datapoint subset to validate setup quickly.
