Inverse Dynamics forces header

Dear all

I am using OpenSim 3.3 and doing some inverse dynamics.
Everything is ok until I load my loads :

Storage: ERROR- failed to parse header of storage file.
InverseDynamicsTool Failed: Storage: ERROR- failed to parse headers of file efforts.mot

my header is

efforts.mot
version=1
nrow=100
nColumns=6
inDegrees=yes
endheader

because I really have 6 columns of 100 values...

Have someone already seen that error?
Could anyone help?

Hi Maxime,

Your time column should be included in your nColumns total (1 time column, 3 forces, 3 location; 7 total).

Cheers,

You are right, that was one of my errors ...

Do you know how OpenSim deals with the different time vectors ?
How does it work if the movement analysis time vector and the force plate time vector are different? (e.g. frequency and spacial offset)

Forces and coordinates are both splined and turned into functions, so different capture rates can be used.
