**Mouse Interactions**

*   **Click + Drag**: Draw a box to select multiple traces (highlighted in red).

.. _ref_classifier_widget:

Classifier Widget
-----------------

**Controls**

*   **Class Name**: Name of the output column (e.g., ``status_alive``) or event (e.g., ``death``).
*   **Feature X/Y**: Select features for the 2D scatter plot.
*   **Log Scale** (:icon:`math-log,black`): Toggle log scale for the corresponding axis.
*   **Project Times** (:icon:`math-integral,black`): Toggle between single-frame view and projecting all timepoints.
*   **Frame Slider**: Browse through timepoints (when projection is off).
*   **Transparency**: Adjust point opacity.

**Classification**

*   **Query**: Pandas-style query string (e.g., ``area > 500 and intensity_mean < 100``).
*   **Preview**: Highlight matching cells in red on the scatter plot.
*   **Apply**: Create the classification column.

**Time Correlation**

*   **Unique state**: Cell enters a state and remains in it.
*   **Irreversible event**: A definitive transition (sigmoid fit).
*   **Transient event**: State can be entered and exited.

*   **Prerequisite event**: Condition must occur after another specified event.

.. _ref_phenotype_annotator:

Phenotype Annotator
-------------------

**Controls**

*   **Phenotype**: The integer label ID (e.g., `0`, `1`, `2`) to assign to the selected cell for the active **Characteristic Group**. This allows you to categorize cells within a specific attribute (e.g., `0` for uninfected, `1` for infected).
*   **Delete cell** (:icon:`delete,black`): Mark the selected cell for deletion.
*   **Add/Delete Characteristic Group**: Create or remove custom grouping columns (e.g., ``group``, ``group_custom``). A **Characteristic Group** represents a specific attribute or classification scheme, and the **Phenotype** is the value assigned to a cell for that attribute. Select the active group from the dropdown menu (default is ``group``).

**Mouse Interactions**

*   **Left Click**: Select a cell to view/edit its group.

.. _ref_interaction_annotator:

Interaction Annotator
---------------------

**Controls**

*   **Neighborhood**: Select the neighborhood definition to visualize (e.g., ``prox_15_px``).
*   **Interaction Event**: Select the event class to annotate (e.g., ``contact``).
*   **Annotation Buttons**:
    *   **Event**: Mark the current timepoint (or time of interest) as the start of the event.
    *   **No event**: Mark the pair as having no event.
    *   **Else**: Mark as "else" (ambiguous or other).
    *   **Mark for suppression**: Flag the pair for removal.
*   **Time of interest**: Manually specify the frame number for the event.

**Signal Visualization**

*   **Reference / Neighbor / Pair**: Select signals to plot for the reference cell, neighbor cell, and the pair itself (e.g., distance).
