Hi, I know that this thread is very old, I just encountered it. But this seems very familiar to me and maybe I may be able to help somebody else who is looking for exactly the same issue in the future. I had a lot of issues when Matlab crashed various times always at different parts of my code unexp...

Hi everybody, since I found a solution to my question, I want to share it here in the case somebody else needs it in the future. The AssemblySolver Class can be used with different weights, I just defined the CoordinateReferencesArray in a wrong way. That's how it is done correctly with Matlab %% CA...

Hi everybody, I am creating a model of a person pedaling with the arms (like handbiking) (Matlab scripting, OpenSim 4.1) To create the movement during pedaling, I created the pedals as a body welded to ground and constrainted both hands to each pedal via two PointConstraints per hand to avoid any cl...

Hi Ayman,

thanks for this advice, it worked

Hi everybody, my university updated the student computers which means that I need to switch from OpenSim 4.0 to 4.1. I developed over the last month my own motion capture analysis in OpenSim using the coding possibilities in Matlab. Prior to the conversion, my code ran without any problems in OpenSi...

Hi, thanks! I work on a university computer which I'd expect to have enough capacity. However, I finally found all the issues and I am not running into the matlab crashes anymore: 1) USE cloneAndAppend and not adoptAndAppend for Markers etc. 2) When you want to use the matlab visualizer, the code ne...

Hi Ayman, Sure I can attach model and mot-file. I'd be very happy if you can help me out. Would you provide me some additional information of file-bugging in the GUI? I didn't know yet that this is possible. Regarding the max number of characters: So if we find another issue causing that exception, ...

Hi,

I realised that when I let my code run without having made any changes, the corrupted mot-file changes.
I have those 6 mot-files (out of 3 models with 2 movements each) and everytime another mot-file throws the index-out-of-bounds-error.

Maybe this helps?

Just as follow up, so that maybe someone else might be helped: The issue of matlab crashes was caused by one final marker.adoptAndAppend(). Once I changed it to marker.cloneAndAppend() the issue was gone. This post helped me: https://simtk.org/plugins/phpBB/viewtopicPhpbb.php?f=91&t=9403&p=25821&sta...

Hi, I use Matlab to create a motion with the IK tool. The input TRC-file is written in matlab, too (no motion capturing). I could successfully implement the IK tool in matlab, it runs trough without throwing any error. I do this for 6 different combinations ( 3 differently scaled models with 2 movem...
