Dear Ayman: Thanks for your response and kind disposition. Well, basically the goal here is to incorporate OpenSIM API's capabilities to a gaitlab workflow. The idea, instead of porting everything to OpenSIM, was to design a simple app that could be incorporated as a optional pipe in between our nor...

Hi! I'm looking for some guidance here. I'm currently working on a Qt app that displays a OpenSIM 3.3 model visualizer, alongside some plots, a scrollbar to loop through some motion coordinates, and not much more. This is all being done in Python (pyqt) Best case scenario question: is there a way to...

Our gaitlab sometimes looses sight of one or two experimental markers. This means that for a few frames we have no coordinates values for these markers, while the rest are OK. Is there a way to express this lack of information in a TRC file? Is there a None, NaN or Null value I could use?

Three years too late, but check this out:

Tom: Thanks for your help! I solved the issue, it hadn't anything to do with coordinates orders: storage values where in degrees. :roll: . I modified the state looping for the unordered state nevertheless. Thank you very much for your assistance! from math import radians def computeLen(mot,mod): sto...

Tom: I just saw you post a very similar answer in another post, but Matlab code. I don't think it's working, muscle lengths are far from what informed in the MuscleAnalysis Tool. Posting here the example function I'm working on: def computeLen(mot,mod): storage = opensim.Storage(mot) model = opensim...

Thanks Tom! I've no trouble looping through a model with its ModelVisualizer on, since at every step I call getVisualizer().show(newState). It works exactly as you show in other Matlab examples I found here. However, without it, how can I loop the model through the different states? I see that the s...

Even worse: had my editor's search set for regex searches

As suggested, I created a MuscleAnalysis and ran it through an AnalyzeTool from python, which worked perfectly. The only info I need right now is the muscle-tendon length of a few muscles. The tool, however, creates a myriad of storage files for moments, forces and angles (all of them empty, with on...

Yep, that's it. I just tried it on a Windows machine with a release install of OpenSIM and works fine. I guess the switch to 4.0 is becoming more and more of a necessity. I'll give it a thought once the compiling instructions for the GUI in Linux are available :lol: By the way, that was opensim.pyc,...
