Batch analyze OpenSim session data

Loads an OpenSim session and performs batch movement analysis using a TaskSchema for event detection and normalization.

Usage

batch_analyze_opensim(
  session_dir,
  schema,
  signal_mapping = list(),
  trials = NULL,
  normalize_method = NULL,
  ...
)

Arguments

session_dir

Directory containing OpenSim output files, or an opensim_session/opensim_workflow object from signalIO

schema

A TaskSchema object defining events and phases

signal_mapping

Named list mapping schema signal names to actual channel names in the data

trials

Character vector of trial names to analyze. If NULL, analyzes all.

normalize_method

Override schema normalization method

...

Additional arguments passed to normalizeMovement

Value

A list containing:

• trials: List of normalized trial data

• events: List of detected events per trial

• phases: List of phase timing per trial

• summary: Summary statistics across trials
