<t>Hello Sherm,<br/> <br/> Many thanks! I followed your advice and successfully compiled a few example files.<br/> <br/> However, I have to add the library names which are linked to SimTKsimbody and SimTKsimbody_aux (more than 20 library files) to the command line. Is there a way to tell gcc to link...

<t>Hello,<br/> <br/> I installed the SimTK Core libraries on linux and AuxInstallCheck and CoreInstallCheck are working fine. However, I have problems compiling the example files using gcc compiler. My latest attempt was 'gcc -I/usr/local/SimTK/include -L/usr/local/SimTK/lib Pendulum.cpp -o Pendulum...

<t>Part of scaling is the adjustment of markers to better match the measured marker position. <br/> How is a particular marker position being adjusted by running the IKMarkerTask? I thought that the result of the IKMarkerTask are generalised coordinates (i.e. joint angles) and not marker coordinates...

Thanks Ayman, pictures are always useful!

I think the question mainly comes up because of the knee joint, which doesn't have a fixed position with respect to pelvis.

Cheers,

<t>Found the answer myself. The CustomJoint 'knee_r', being local coordinate system of Body 'femur_r', is translated in x and y with respect to parent 'pelvis' so that the translational DOF in the knee can be captured. Body 'tibia_r' is then loaded as child of 'femur_r' at [0 0 0] location_in_parent...

<t>I have a question related to this thread. The .osim file doesn't seem to contain any information about the location/origin of a body's reference frame. Where does this information come from? Is it somehow stored in the .vrt file? I am looking at the gait2354_simbody.osim file. Tibia is loaded as ...

<t>Hi Daniel,<br/> <br/> Thanks for your quick response and the copy-paste suggestion! <br/> <br/> Looking at the MOT files in the examples, I think it should be possible to copy paste my data into this file. However, is there any documentation which outlines angle convention and position/direction ...

Hi there,

I would like to run a gait simulation (inverse dynamics) using OpenSim. However, I only have ASCII files of the kinematic data (marker coordinates or joint angles). Can I input those files to run a simulation?

Cheers,

Katja
