Hi Sheeba, 1. The original model didn't have all the markers that are in the dataset and also the names were different. so I changed the marker names according to the dataset and also introduced new markers (placed them manually) to make sure that it has all the markers that are present in the datas...

Perfect, I hope it went well.

Hi Sheeba,

1. For the scaled model, how far is it displaced? How far is the model relative to the displayed coordinate system?

2. Where are your .vtp files located? Check to see if you model in the .xml file is calling the correct .vtp file for the femur and tibia.

I hope this helps

Hi Sudip, You can add a constant force through the GUI as an external force to the desired segment (i.e., hand). You will also need to create a .mot file that will specify the force profile throughout, for example, the trial that you are performing the analysis on. The procedure is similar to adding...

Hi Sheeba, To my knowledge, the procedure for the most part seems correct. One potential issue could arise from placing the new markers on the model and whether or not those markers were used for scaling. If they were used for scaling (e.g., a marker on the distal end of segment) and either the mode...

Perhaps look at the moment arm of each muscle separately? The best approach may depend on your research question. Yes, I want to calculate the moment arm of each desired muscle during movement. I mean after this calculation I should have a time-table with the first column of time, plus columns that...

Hi Hmaed,

In the past, I have used "dlmread" in Matlab to import the coordinate data of a .mot file and then "readtable" to extract the variable names.

I hope this is helpful

Hi Jianlin, My suggestion would be to check out this project: https://simtk.org/projects/ceinms It might be able to help you get up an running with using EMG with MSK modelling. My other thought would be to try implement something a bit more simple such as an EMG assisted static optimization with th...

Hi Mohammadreza, The IK needs a model to run procedure. My thoughts are that you scaled you model and the .mot file is the posture (coordinates) of your scaled model. When you run IK, you need a model, which if I understand correctly, is your scaled model. If you run IK with or without the .mot file...

Hi, What type of contraction or movement are you trying to make this comparison for? For example, do you have data from an isometric contraction in a dynamometer vs something more dynamic like walking? Most static optimization routines will have the tendon as rigid and then simply, based on the obje...
