Prescribe Motion to OpenSim Model

Description

This function prescribes motion to the coordinates of an OpenSim model based on inverse kinematics (IK) data. It can save the modified model to a file or return the updated model object. Note that the input model must already have any locked joints welded prior to using this function.

Usage

prescribe_motion_osim(
  model_input_file = "model_file.osim",
  model_output_file = "model_prescribed.osim",
  IK_file = "IK.mot",
  low_pass_cutoff = 6,
  write_file = TRUE,
  return_object = FALSE
)

Arguments

model_input_file	A string specifying the path to the input OpenSim model file (default is "model_file.osim").
model_output_file	A string specifying the path for the output updated OpenSim model file (default is "model_prescribed.osim").
IK_file	A string specifying the path to the IK data file (default is "IK.mot").
low_pass_cutoff	A numeric value specifying the cutoff frequency for the low-pass filter (default is 6). Will be ignored if this is not a numeric value >= 1.
write_file	A logical value indicating whether to write the updated model to a file (default is TRUE).
return_object	A logical value indicating whether to return the updated model object (default is FALSE).

Value

If 'return_object' is TRUE, returns the modified OpenSim model object; otherwise, NULL.
