RRA

Post by rajat das » Mon Jan 09, 2017 2:23 am

Hi,

I am using RRA for a file which is 134 sec long. How ever after running for 32 sec opensim is getting closed.

1. In the "vtklog" file it is showing

"ERROR: In \eran\dev\Vtk\Graphics\vtkTensorGlyph.cxx, line 122
vtkTensorGlyph (42E3F5C0): No data to glyph!"

2. I am attaching a portion of "out.txt" file also. Request your feedback, what possible can be go wrong ?

Could the issue be related to the jump from t=0.533 to t=30.812?

Thank you Tom.

Actually my data is related to double limb standing and then single limb standing. There should not be any jump related data. May I know why you are telling that ?

There appears to be a jump (gap) in your data between t=0.533 and t=30.812 (see lines 391–392 in your out.log file). I would expect such a gap to be problematic. Please refer to the "How RRA Works" page on Confluence (http://simtk-confluence.stanford.edu:80 ... +RRA+Works), under the "Tracking Simulation" heading.

As the log file size is big that's why I have deleted few line. Otherwise I was not able to attach it.

Thank you for providing this information. Have you reviewed all the tips listed under the "RRA Settings" and "Troubleshooting" headings on the "Getting Started with RRA" Confluence page (http://simtk-confluence.stanford.edu:80 ... d+with+RRA)? I suggest starting with "Troubleshooting" item #2.

Hi Tom thanks.
I have tried increasing the force of Residual actuators but opensim stops much earlier.

I need some more help. Kindly clarify.
1. In the model .osim file we have "optimal_force" which is always '1' for all the muscle , is this is some standard for normal human being ?
2. Here in the model .osim file the "isometric_force" is some different value for different muscle ? is these are standard values for normal human being?
3. In "gait2354_RRA_Actuators.xml" file we have both Residual and Reserve actuators "optimal_force" , how to decide those values? Is more value means that model muscle is weak ? Or does it mean actually ?
