Hi Madeleine, why not use MOtoNMS to convert your C3D files to Osim formats? It is compatible with Kistler FPs and the code can be tweaked to make the process more automated.
MOtoNMS is flexible but can be tedious if you have lots of gait data. How many trials do you/will you have?
Cheers
Jas

Re: Batch AnalyzeTool: java:154 error
Managed to fix this issue using the following approach suggested by James Dunne on a different post discussing issues appending actuators and external loads to a template SO_setup file. " This seems similar to previous issues I have had with changing the external loads file when using a pre-existing...

Batch AnalyzeTool: java:154 error
Hi, I am using the AnalyzeTool in matlab to loop over a series of motion trials. It successfully processes the first 2 trials and then I get the below error on the third file: "" Error using setupAndRunStaticOpBatch2 (line 182) Java exception occurred: java.io.IOException: ExternalForce: Data source...

Hip Center Manual Scaling
Hi, I am trying to scale the pelvis of the Gait2392 model and I have a 'known' HJC location in pelvis frame from CT I have computed externally. Can I use the difference in hip joint center locations between the 2392 and my model to apply manual scale factors for the pelvis of 2392? When I try this t...

Low Joint Reaction Force
I ran the analysis function to estimate joint contact loads of the hip on the acetabulum in the femur during pathological gait and got a joint reaction of 0.4BW. The patient's gait appears to have a clear stance phase so clearly less than 1BW is not accurate. What are the steps to take to generate a...

Re: Modifying geometry in OpenSim
Okay I see what you mean. If I import an STL with different geometry to the 2392 file, this would obviously effect the new muscle attachments points won't it?

Re: Modifying geometry in OpenSim
Thanks for your response Daniel. So I simply modify the geometry in notepad ++ using the x,y,z in the parent (i.e. pelvis)? Is there also a way to change this in the OpenSim GUI?

Modifying geometry in OpenSim
How do I modify the geometry of the femur in OpenSim, i.e. change in hip joint centre location, femoral anteversion and femoral neck length. I can determine the geometry in an external software from a segmented bone but am not sure how to then modify/scale the model in OpenSim to match. Any help wou...
