Giorgio Gilestro 2623df4172 Picker: identify the analyst (initials) per pick 
Each annotation row now carries an `analyst` column. On first visit the
web picker shows a small login modal asking for initials, persists them
in localStorage, and shows the badge in the top-right. Click the badge
to change identities. Submissions without initials are rejected by the
backend (HTTP 400). Skip remains analyst-free.

Backfill: every existing barrier_opening.csv row marked as `GG` since
all current picks were done by Giorgio.

Cupido — web-based barrier-opening picker

A small FastAPI + HTML5-video app for annotating the barrier-opening moment in each tracked recording. Lives in its own Docker container so it can run on the lab server without polluting any existing environment.

What it does

For every video referenced by all_video_info_merged.tsv that has a tracking DB on disk and isn't yet in barrier_opening.csv, it serves a <video> element pre-loaded with that mp4. The analyst plays / scrubs / pauses at the moment the barrier opens, then clicks one of:

button meaning written to bad_rois
All barriers open every ROI (1..6) is usable post-opening empty
Upper barriers open only the top row opens (ROIs 1, 3, 5) 2,4,6
Lower barriers open only the bottom row opens (ROIs 2, 4, 6) 1,3,5

Plus a Skip (advance without saving) and Unusable (write opening_s = NaN).

Keyboard shortcuts

  • Space — play / pause
  • ← / → — ±5 s
  • Shift+arrows — ±1 s
  • Ctrl+arrows — ±0.1 s
  • , / . — ±1 frame
  • 1 / 2 / 3 — All / Upper / Lower
  • s — skip ; u — unusable

Run locally (docker compose)

cd scripts/barrier_picker_app
docker compose up --build

Then browse to http://localhost:8085/.

The container mounts:

  • /mnt/data/projects/cupido (data volume, read-only)
  • /mnt/ethoscope_data/videos (source mp4s, read-only)
  • data/metadata/ from the repo (read-write — for persisting barrier_opening.csv)

Adjust paths in docker-compose.yml if your layout differs.

Run without Docker (development)

cd scripts/barrier_picker_app
pip install -r requirements.txt
python app.py     # serves on http://localhost:8000

By default it expects:

  • merged TSV at /mnt/data/projects/cupido/all_video_info_merged.tsv
  • inventory at /cupido/data/metadata/video_inventory.csv
  • writes to /cupido/data/metadata/barrier_opening.csv

Override via environment variables:

CUPIDO_DATA_VOLUME=/path/to/data \
CUPIDO_INVENTORY_CSV=$(pwd)/../../data/metadata/video_inventory.csv \
CUPIDO_OUTPUT_CSV=$(pwd)/../../data/metadata/barrier_opening.csv \
python app.py
