Hi
I have EMG voltage data of MCP2 with respect to time.So can I use static optimization method by uploading those data as .mot file

What you can do is: extract the emg envelope and use it to constraint the possible solution that the SO or CMC finds. Here is how to constrain CMC:

Ok I Will try this method.
Also I would like to know about an option in muscle properties .The option is max control and min control which specifies numerics that can be edited.What does that numerics denote.One of the video lectures goes by saying that it would increase the muscle power.So does it mean that withstanding large forces at a short time ?

This is a property of an Actuator. For the muscle it always lies between 0.01 and 1, and for other actuators it can have different bounds.

Could you mention what exact steps I should follow from the link given to convert the voltage data of emg to a .mot file which should have equivalent angle values .

Hi Krishnakumar,
You can use MOtoNMS "https://simtk.org/projects/motonms" to extract the emg envelope from C3D files.

I have only a .sto file which has emg data namely time and voltage and not any other data.My doubt is whether is it possible to convert the data I have to equivalent muscle force ?

"XML file for the CMC setup file".The link has this code.Is this the code to be edited for my application of converting voltage to angle.
