# Bio-IT Workshop Session Journal

This document records the interactions and actions taken by the user and Gemini CLI during the workshop session.

## Phase 1: Initial Setup (Quest 1)
*   **Action:** Started the workshop with Quest 1 (`01_QUEST_START_HERE.md`).
*   **Prompt:** User selected "The Starry Night" for the initial dashboard color palette.
*   **Action:** Generated mock single-cell data (`src/generate_mock_data.py`) and built a web dashboard (`web/index.html`, `web/visualization.js`) using the Starry Night theme.

## Phase 2: Writing the Data Processing Spec (Quest 2)
*   **Prompt:** User asked for suggestions on validation tests to include in the markdown file (`02_QUEST_FIG3.md`).
*   **Action:** Brainstormed validation tests focusing on dimensionality, concordance, handling unknowns, and sanity checks.
*   **Prompt:** User answered brainstorming questions (2 dimensions, check paper for concordance metric, check for errors on unknowns).
*   **Action:** Consulted the "teacher's cheat code" (`02_SPEC_ANSWERS.md`) to find the expected concordance metric (percentage agreement heatmap). Proposed specific text for the SPEC document.
*   **Prompt:** User requested to replace the placeholders in the document with the proposed text.
*   **Action:** Updated the 'VALIDATION Tests' section in `02_QUEST_FIG3.md`.
*   **Prompt:** User provided brief answers for the remaining placeholders (Figure 3 descriptions, cell label terminology, outputs).
*   **Action:** Replaced the remaining placeholders in `02_QUEST_FIG3.md`.

## Phase 3: Processing Real Data & Theming
*   **Prompt:** User confirmed readiness to start writing the script to process real data.
*   **Action:** Downloaded the Kretzler kidney dataset (`kretzler_kidney.h5ad`), symlinked the SCimilarity model, and wrote `src/process_data.py` to process the data and generate real JSON outputs.
*   **Prompt:** User requested changing the heatmap coloring to match the original paper.
*   **Action:** Changed the Plotly heatmap colorscale to the standard scientific `'Blues'`.
*   **Prompt:** User requested changing the theme away from Starry Night, specifically requesting the "viridis colormap".
*   **Action:** Updated the Python script to use Matplotlib's `viridis` colormap for the UMAP categories and changed the web dashboard to a clean, light "Modern Academic" theme to complement the Viridis colors.
*   **Prompt:** User requested making the ordering of the labels the same in the heatmap.
*   **Action:** Modified the pandas crosstab logic in `src/process_data.py` to use consistent categorical ordering for both axes, ensuring a perfectly aligned square matrix.
*   **Prompt:** User requested plotting the overlapping annotations for the heatmap.
*   **Action:** Added a "Show Only Overlaps" toggle to the UI that masks off-diagonal elements in the heatmap.

## Phase 4: Teacher's Specifications & Unit Tests
*   **Prompt:** User requested to refer to and adapt to the "teacher's cheat code".
*   **Action:** Implemented features from `02_SPEC_ANSWERS.md`: 
    *   Added text annotations for percentages > 5% on the heatmap.
    *   Reverted heatmap colorscale to 'Blues'.
    *   Changed toggle to "Show only disagreements" (filtering UMAPs).
    *   Added a custom interactive HTML legend.
    *   Updated processing script to output to `results/data_subsample/` and generate a static `concordance_heatmap.png` in `results/figures/`.
*   **Prompt:** User requested to write automated unit tests.
*   **Action:** Created `tests/unit/test_process_data.py` testing gene alignment logic, label harmonization, and concordance matrix structure. Tests ran successfully.

## Phase 5: Reverting and Recreating
*   **Prompt:** User requested to revert all changes and recreate the project.
*   **Action:** Deleted all generated code (`src/`, `web/`, `tests/`, `results/`), downloaded data, and reverted `02_QUEST_FIG3.md` back to its original template state.
*   **Prompt:** User requested to get started again.
*   **Action:** Restarted Quest 1, asking for a new color palette choice.
*   **Prompt:** User selected "composition with red blue and yellow" (Mondrian).
*   **Action:** Rebuilt the project skeleton, mock data generator, and web dashboard using a custom Mondrian aesthetic (stark borders, primary colors, white canvas).
*   **Prompt:** User requested to move to Quest 2.
*   **Action:** Asked how to handle the placeholders in `02_QUEST_FIG3.md`.
*   **Prompt:** User requested using the teacher's answers to fill the placeholders.
*   **Action:** Auto-completed the SPEC document.
*   **Prompt:** User confirmed to proceed with real data processing.
*   **Action:** Re-downloaded the dataset, rewrote `src/process_data.py` to handle real data while maintaining the Mondrian palette, and updated the UI with the advanced filtering features.

## Phase 6: Wrap Up
*   **Prompt:** User requested a journal of the prompts and actions.
*   **Action:** Created this `JOURNAL.md` file.
