Re: Scaling problem - RASI & LASIS issue

Hello, Thank you a lot for the input! I managed to improve my scaled model! One more question...I have the same subject pre and post surgery and I am trying to use the same scaled model I used for pre in post (6 months after). I believe I only need to adjust the markers model (of the post motion cap...

Scaling problem - RASI & LASIS issue

Hello I am having issues with the scaling process and hopefully some of you might have more experience with this particular problem! The resultant scaling gives me a very big hip (which might also be causing some foot scaling problems) and I manually make an adjustment of virtual markers location to...

Inverse dynamics problem

Dear all I am running static optimization (SO) and it fails for some of my subjects. I am trying to figure out if it comes from the inverse dynamic process or if the problem is in that my model is weak and so on. I have plotted the output of inverse dynamics (ID) and it concerns me since something s...

Hello all, I am running into an issue after scaling that maybe you have encountered and could possibly orient me in the right direction. It might be something simple but I have troubles to figure it out. I have noticed that for some of my subjects scaling seems ok but for others the hip seems to be ...
