Setup Inverse Kinematics XML — setup_inverse_kinematics

This function sets up an XML file for inverse kinematics by modifying a given base XML file with the specified parameters (e.g., model, marker data, time range, etc.) and saves the updated XML file to a specified filename.

Usage

setup_inverse_kinematics_xml(
  base_file = "setup_ik_base.xml",
  results_directory = ".",
  model_file = "model_scaled.osim",
  constraint_weight = "Inf",
  accuracy = "1e-005",
  marker_file = "marker_data.trc",
  coordinate_file = "Unassigned",
  start_time,
  end_time,
  report_errors = "true",
  output_motion_file = "ik.mot",
  report_marker_locations = "true",
  Markers,
  Weights = rep(1, length(Markers)),
  setup_filename = "setup_ik.xml"
)

Arguments

base_file: A character string specifying the path to the base XML file. Default is "setup_ik_base.xml".
results_directory: A character string specifying the directory for saving results. Default is the current directory (".").
model_file: A character string specifying the path to the scaled model file. Default is "model_scaled.osim".
constraint_weight: A character string or numeric specifying the constraint weight. Default is "Inf".
accuracy: A character string or numeric specifying the desired accuracy. Default is "1e-005".
marker_file: A character string specifying the path to the marker data file. Default is "marker_data.trc".
coordinate_file: A character string specifying the path to the coordinate file. Default is "Unassigned".
start_time: A numeric value specifying the start time of the simulation.
end_time: A numeric value specifying the end time of the simulation.
report_errors: A character string specifying whether to report errors ("true" or "false"). Default is "true".
output_motion_file: A character string specifying the output motion file name. Default is "ik.mot".
report_marker_locations: A character string specifying whether to report marker locations ("true" or "false"). Default is "true".
Markers: A character vector specifying the names of the markers used in the inverse kinematics setup.
Weights: A numeric vector specifying the weight for each marker. Default is a vector of 1's with the same length as `Markers`.
setup_filename: A character string specifying the name of the output setup XML file. Default is "setup_ik.xml".

Value

The function does not return a value. It writes the modified XML to the specified setup_filename.
