How to exactly rotate the data in Tables

Hi all, I am trying to replicate the osimC3D script made by you in Matlab into python, especifically I am building the rotateTable function to rotate some axis in the markers and force tables. I have the following code: def rotateTable(self, table, axisString, value): value_rad = np.deg2rad(value) #...

Re: C3D reading exception

I realized that is a ezc3d issue, they do not admit another format characters in the USED section.

C3D reading exception

Hi all, Thanks for continue developing. I am having problems trying to read a C3D file from the C3DFileAdapter() , It throws an exception: RuntimeError: std::exception in 'OpenSim::DataAdapter::OutputTables OpenSim::DataAdapter::read(std::string const &) const': USED parameter is not an INT I do not...

Re: Many question for API management

Thanks to both for the answers: Unfortunately, for the first one, it didn't work. I tried in the following way: sto = osim.Storage(Dir + "/" + IK_results) table = sto.getAsTimeSeriesTable() print(table.toString()) But I got the next error: AttributeError: 'SwigPyObject' object has no attribute 'toSt...

Many question for API management

Hi all, I was trying to do a lot of things in Python's API but I found some errors that I would like you to solve or help. Probably, These errors occur because I don't understand well the architecture of OpenSim. The errors are shown below: 1. When I try to print an array, what it is printed is the ...

Re: RRA forces calculations does not match with ID

Basically, checking the residuals, these are in the good range, so I think that something is not good because kinematics are well simulated by RRA but dynamics are not. By the way, I'm reproducing the study the study from Liu, nothing was changed, so I think the process of simulation were doing well.

RRA forces calculations does not match with ID

Hi all, I am doing a research related to forces at the ankle joint, trying to get the quasi-stiffness of this joint. There are some cases that we cannot obtain ID just because we don't have external forces. So, the other option is to calculate forces through RRA tool. Using this tool We observe that...

Problems with scripting in matlab 2014b 64 bits

Hi, I'm working with linux (specifically ubuntu 14.04). I installed Opensim 4.0 - 64bits with simbody 3.6. In addition, I checked Java wrapping to work with Matlab 2014b 64 bits. Everything was fine until the moment to fix matlab with opensim. When I ran the configure file an error showed the next m...
