Tab 4 — Processing

Runs the Pose2Sim pipeline (included as a git submodule at code/pose2sim/) on recorded trials.

🚧 TODO: screenshot.

Running

• Tick trials in the tree view (grouped by session) and click Process Selected.
• Trials run sequentially, with live log output streaming in the GUI. Stop halts after the current step completes.
• On success, the trial is flagged processed: true in its trial.json.

What happens per trial

1. Stage — trial data is laid out in Pose2Sim's expected directory structure ([trial]/processed/).
2. Validate — synced videos, the calibration TOML and participant height/mass must all exist.
3. Run — pose estimation (RTMPose via CUDA) → triangulation → Butterworth filtering → OpenSim kinematics.

Requirements & gotchas

• NVIDIA GPU effectively required — CPU runs are impractically slow.
• The participant must have height and mass set (used for OpenSim model scaling).
• Re-running a trial can leave stale files behind — see Known issues.

🚧 TODO: output reference — what lands where after processing (.trc, .mot, scaled model, IK results) and how to open results in OpenSim. Link the repo's docs/pose2sim_integration.md for technical detail.
