Your First Session
This page walks through creating a new session and orienting yourself to the RIME interface.
Create a new session
Launch RIME (rime in terminal), then open the Session Wizard via Session → New Session (Ctrl+N).
1. Session info
| Field | Description |
|---|---|
| Session folder | Root folder where session.json and annotations.json will be saved |
| Session name | Auto-filled from the folder name; edit if needed |
| Rater ID | Optional — identifies the annotator |
| Subject ID | Optional — identifies the participant |
| Condition | Optional — e.g. OFF medication, ON medication |
| Medication state | Optional |
2. Schema
Select a protocol schema from the dropdown. Schemas define the annotation lanes, labels, and rules used in your study.
- Notes Only — minimal schema, a single free-text lane
- GP-FOG — the Giladi Protocol FOG schema (Gilat et al., 2026)
If you are setting up a new study with a custom schema, see Protocol & Schema first.
3. Media files
Add the video and signal files recorded for this session.
Videos (up to 5, optional):
- Supported formats:
.mp4,.mov,.avi - The first video added becomes the primary view; additional videos are secondary
Signals (optional):
- Supported formats:
.csv - Adding a signal file opens the Signal Configuration dialog — see Signal Configuration
4. Create
Click Create. RIME writes session.json and annotations.json to the session folder and opens the session.
