C3D Extraction Toolbox

[mehri makki]

Hi everyone,

After successful installation of toolbox, I tried to run testwalk.m, but I face with some errors:

???Invoke Error, Dispatch Exception:
Source 3DServer.C3D.1
Desciption: File not found in specified location

Error in ==>openc3d at 43
pRet = itf.Open(file,3);

Error in ==> getEvents at 160
open3d(itf, 0, C3Dkey.c3dFileFull);

Error in ==> testwalk at 26
keySta = getEvents(c3dFileStatic, 2);

Does anybody have idea?
Thank you.

That error occurs when you have incorrectly specified the location or name of the file which you wish C3D server to open. Check that you have correctly entered the path to the file as well as the file name. Also make sure to include the extension (e.g. .c3d) of the file!

Hi everyone,

I, too, have been experiencing some difficulty running testwalk.m. However, this is the error message that I get:

??? Error using ==> actxserver at 91
Server creation failed. Invalid ProgID 'C3DServer.C3D'

Error in ==> c3dserver at 24
itf = actxserver('C3DServer.C3D');

Error in ==> getEvents at 159
itf = c3dserver();

Error in ==> testWalk at 26
keySta = getEvents(c3dFileStatic, 2);

I have the path saved correctly. I am not sure why there is an error with the server creation. I have the MLS Viewer in the same folder as the GaitToolbox, which is also saved to the path. I heard that there might be issues with 64 bit version of Matlab, but I am using the 32-bit 2010a version. Can anyone offer any feedback?

Thanks,

Hi Brooke & All,

I'd suggest you contact the "toolbox" author and the mailing list there

as they may be able to help you better.

Good luck,

Hi all,

If you use VICON motion capture systems,
please try our toolbox which directly converts VICON motion capture data(*.csv) into OpenSim inputs(*.trc and *.mot).
This is much easier and faster than converting C3D files.

Please refer to our project page: https://simtk.org/home/lee-son/
The toolbox v.1.4.1 is already available, but the user manual is now in preparation.
If you have any questions in using our toolbox, please contact us.
