markers.parquet: Time series of marker positions (x, y, z) per frame
forceplates.parquet: Force plate forces, moments, COP per frame
events.parquet: Gait events (Left/Right Foot Strike, Foot Off)
sessions.parquet: Mass, bone lengths, joint centers per session

Usage

import polars as pl

# Load markers for a subject
markers = pl.read_parquet("processed/BAA01/markers.parquet")

# Filter to a session
baseline = markers.filter(pl.col("session_id") == "baseline")

# Get unique trials
trials = baseline["trial_name"].unique().to_list()
