Hi all I want to use an objective function that minimize an error in scriptmeasure. Actually, I have defined a new variable at script controller, and I want to use the error (difference between the new variable and joint angle) in scriptmeasure. But as far as I know, I can't import a variable define...

Hello Thomas I have a specific question, and am appreciate to help me. I want to reset time my controller at each gait cycle meaning at the beginning EarlyStance. in fact, my controller runs for these states: "EarlyStance LateStance Liftoff Swing Landing". if I use the reset time code you mentioned ...

Dear all I want to measure muscle forces of a patient who has abnormal gait using static optimization. Do I need the specific osim model of the patient to measure these forces and activation as well? or It's OK to use normal osim model of openism? Can you give me articles that refer to this issue? B...

Thanks Mohamadreza

I think it works well.

Hi

I would like to use a metabolic cost including some muscles not all of them. Could you guide me how to exclude some muscles from Measure function like Uchida2016 or others?

Hi I want to know how I can extract one gait cycle from a simulation results. For example, I have done 10 second gait simulation but I would like to display one gait cycle that I have extracted manually so far (from heel strike to next heel strike). Is there any code to extract it based on GRF? Best

Hi Thomas

I changed the name of body to calcn_r but ground reaction force is still zero, while it isn't.

body = model:find_body("calcn_r")
GRF = body:contact_force()

Could you pls guide me how to get ground reaction force?

Hi

I did it. No effective. I use this code to get the result of GRF:

function store_data(frame)
frame:set_value("GRF",GRF)
end

Is it true?

Many Thanks Thomas for your quick reply. May you tell me how to call A in form of a table? I changed my main code to ask my question. In fact, I want to obtain the length of time vector at instance time. So by having time step, I create this vector to record time. In this case we have: function upda...

Hi I would like to create a vector in script lua like this: A = 0:0.1:1. It means A starts from 0 and stops at 1 by step 0.1. To create this vector in Lua, I used the following code: A = {} function init(model, par) end function update(model) local start = 0 local stop = 1 local step = 0.1 for i = s...
