compute_muscle_length_anatomical: Compute Anatomical Muscle Lengths from an OpenSim Model

In Kneerav/biomechanics: Biomechanics Data Analysis

Compute Anatomical Muscle Lengths from an OpenSim Model

Description

Extracts muscle-tendon unit (MTU) lengths from a static OpenSim model at its anatomical (neutral) posture.

Usage

compute_muscle_length_anatomical(
  model_file = "../TestData/Model_SCALED.osim",
  file_output = "muscle_length_anatomical.sto",
  write_file = FALSE,
  return_object = TRUE
)

Arguments

model_file	Path to the '.osim' model file (OpenSim 4.x format).
file_output	Name of the output file to write muscle lengths (optional).
write_file	Logical. If 'TRUE', writes output to a '.sto' file.
return_object	Logical. If 'TRUE', returns a data frame of muscle lengths.

Value

If 'return_object = TRUE', returns a data frame with muscle lengths at time = 0. Otherwise, returns invisibly.
