Compute Moment Arm Curve for a Muscle-Coordinate Pair in an OpenSim Model
Source:R/compute_moment_arm_curve.R
compute_moment_arm_curve.RdThis function computes the moment arm curve for a specified muscle and coordinate in an OpenSim model, iterating over the coordinate's range. The moment arm is calculated at increments of a specified angle and can be written to a file or returned as a data frame.
Usage
compute_moment_arm_curve(
model_input_file = "../TestData/Model_SCALED.osim",
coordinate = "knee_angle_r",
muscle = "vasmed_r",
file_output = "vasmed_r_knee_angle_r_moment_arm.sto",
deg_increment = 10,
write_file = FALSE,
return_object = TRUE
)Arguments
- model_input_file
A string representing the path to the OpenSim model file. Default is "../TestData/Model_SCALED.osim".
- coordinate
A string indicating the name of the coordinate of interest. Default is "knee_angle_r".
- muscle
A string indicating the name of the muscle of interest. Default is "vasmed_r".
- file_output
A string representing the file path to write the moment arm data. Default is "vasmed_r_knee_angle_r_moment_arm.sto".
- deg_increment
The angular increment (in degrees) for which the moment arm will be computed. Default is 10.
- write_file
Logical: If TRUE, writes the moment arm values to a file. Default is FALSE.
- return_object
Logical: If TRUE, returns the moment arm data as a data frame. Default is TRUE.
