Hi OpenSim-users,

For our study we have to perform the joint reaction analysis and muscle analysis for a lot of trials. Because performing all trials manually in the Analyze-tool in OpenSim is very time demanding, we want to use Matlab to perform these analysis all in ones. However, when using de option 'AnalyzeTool' in Matlab, Matlab crashes and gives the error in the attachment. Is anyone familiar with this problem and knows how to solve this problem?

We succeeded to perform de InverseKinematicsTool and InverseDynamicsTool in Matlab, so we are wondering why this AnalyzeTool does not work.

Hi Lars,

I recall encountering this problem but I'm not 100% sure if this is the right solution. I assume you are creating the AnalyzeTool and then calling it using AnalyzeTool.run(). Something I've found that can solve these random crashes is to save the tool - i.e. AnalyzeTool.print('file.xml') - and then reload the tool to run it - i.e. runTool = AnalyzeTool('file.xml') > runTool.run()

This might solve your problem, but it also might not...

Hi Aaron Fox,

First of all, thank you very much for your quick response.

We did some changes in de xml-file and now it is working pretty fine. We have one last question about the AnalyzeTool. To perform a Joint Reaction Analysis we have to select a force_file in the AnalysisSet (in the attached xml-file: AnalysisSet.objects.JointReaction.forces_file). This force_file has to change for every subject and trial but we don't know how to do this in de xml setup file.

For the other options in the xml-file we simple use the code below, but for this force_file we don't know what kind of code we need to change this parameter for every trial (i.e. we want to use the outname (Sub01_278ms_level) as a variable in this xml-line for the force_file but we don't know the right method to do so).

analyzeTool = AnalyzeTool(fullfile('JRA_tool_set-up.xml'));
analyzeTool.setName(outname);
analyzeTool.setModel(MyModel);
analyzeTool.setModelFilename(char(model_in));
analyzeTool.setResultsDir(output_jra);
analyzeTool.setInitialTime(Times(1,1));
analyzeTool.setFinalTime(Times(2,1));
analyzeTool.setExternalLoadsFileName(fullfile(path_output,['ExternalLoads\' outname '_ExternalLoads.xml']));
analyzeTool.setCoordinatesFileName(IkFile);
analyzeTool.setLowpassCutoffFrequency(ik_filter);
analyzeTool.print(fullfile(setupid_jra,[outname '_JRA_setup.xml']));
analyzeTool.run();

Hi,

You can run Analyze tool directly by the following changes:

Code: Select all

model = Model(PATH_TO_MODEL);
state = model.initSystem();

analyzeTool = AnalyzeTool(model);
analyzeTool.loadStatesFromFile(state);

You can also access to the JointReaction properties by calling the tool and appending it to the analyzeTool:

Code: Select all

JR = JointReaction()
JR.setForcesFileName(PATH_TO_FORCE_FILE)
frame = osim.ArrayStr()
frame.set(0, 'child')
JR.setInFrame(frame)

analyzeTool.getAnalysisSet().cloneAndAppend(JR)
analyzeTool.addAnalysisSetToModel()

Hope this helps.

Regards,
Mohammadreza

Hi,

Thanks for you reply Mohammadreza Rezaie. Now it's clear how to use the Joint Reaction in the AnalyzeTool in Matlab. In this way it's also possible to change the joints, bodies en frames of the joint reaction forces.

Hi All,

I am encountering a similair problem. My Matlab often crashes or closes alltogether when I am running my adjusted run_analyze script (My script runs both the SO and JRA). I have adjusted my model according to the proposal of Aaron. This however, does not seem to work for me. Would anyone be able to tell me what could cause my model to crash? I have added my custom code down below.

I have written the code to sequentially analyze 1 .trc file with the corresponding scaled model. The required model scaling and IK is done using different script. the variables yourfolder and yourfolder2 direct Matlab to the proper folder on my computer.

The Matlab Crash Report gives the following description:
