Hello, I am trying to add a PointToPointSpring between the hand and the handle of a device in my model and keep this force active when performing RRA. Currently, I can use Matlab to add the springs to the OSIM model just fine, but I cannot get the sockets to print to the XML file being used to repla...

Thanks so much for the quick response.

Yep! Making a new RRATool object that was initiated with the made set-up file totally worked. Thanks for the tip!

I do also have the full path of the filename in the set-up file. I saw the note about that being a possible issue on github.

Thanks again,
Evan

Hello all, I am trying to script my RRA in Matlab. I have written a script to set up the RRA Tool and I can print that set-up file from Matlab. If I load that RRA set-up file into the RRA Tool in the GUI and press run, OpenSim calculates as expected. However, if I attempt to run the tool in Matlab (...

Hello, I was wondering if it is possible to use a contact model as the external force input used during the reduced residual analysis? Currently, if I run my model, which includes a foot contact model, through RRA attempting to follow results from inverse kinematics and with the vertical pelvis cons...

Hello, I am working on using the analysis tool (AnalyzeTool) through the Matlab scripting interface to get out the ForceReporter results. When I set up this analysis using Matlab I am using a coordinates file to supply the motion for the analysis and am getting an error that I must supply the states...

Hello, I am trying to show the forces that are applied during the inverse dynamics simulation I am working on. I have run the simulation and I have IDResults under Motions in the Navigator pane. I can then add the Force MOT file to those results as "associate motion". When I do this no force vectors...

Hello, I am trying to change the marker set on an existing model because we would like to try a different model on data we have collected previously. When I open the model with the new marker set in the GUI all of the markers are in the correct locations and on the correct segments. I can then scale...

Yep that's the filename, mine just loops a bunch of trials so that's how it formats to read. I think from what you gave yours would be: motAsTable = readtable('subject01_walk1_grf.txt'); outputs = motAsTable.Properties.VariableNames; data = table2array(motAsTable); Yeah, the mot file is just saved a...

Hey, I was actually working on this today. Here's what I came up with: IKrez_0 = readtable([trialname,'_0_IKrez.txt']); outputs = IKrez_0.Properties.VariableNames; data = table2array(IKrez_0); The input to the readtable is a string of the file name for the inverse kinematics results. I had them prin...

I have attached a shortened version of the TRC that was not working. I opened them in a couple formats and couldn't find any formatting errors. Maybe there's another editor I should open it in? If the Vicon Nexus to TRC pipeline is systematically or randomly putting in spaces instead of tabs though,...
