Re: How to use TimeSeriesTableQuaternion.appendRow in python?

Hello @Thomas, I've tried your suggestion. Unfortunately, it didn't work :( import opensim as osim qrowvec = osim.RowVectorQuaternion(2) qrowvec.set(0, osim.Quaternion(1,0,0,0)) """ Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'RowVectorQuaternion' object ha...

Re: How to use TimeSeriesTableQuaternion.appendRow in python?

Hi, Following-up my last question. When doing qrowvec = osim.RowVectorQuaternion(2) qrowvec[0] = osim.Quaternion(...) I get the following error TypeError: 'RowVectorQuaternion' object does not support item assignment Also, my goal is to simulate an individual movement in real time using data collect...

Re: Mirroring right arm to the left on scapulothoracic model

Dear OpenSim community, My team is still facing issues mirroring the right side to the left on the scapulotoracic model. When dealing with flexio and elevation movements, the coordinates show, for the left side, double the value of the right side and inverted sign, respectively, e.g., right shoulder...

Adjust IMU orientation according to anotther IMU as reference

Hello, I'm analysing an individual's movement using an upperbody model adapted from the scapulotoracic model. Using Inverse Kinematics everything works fine if the individual moves only the arms and shoulders, however, if the individual moves the torso, by inclining or rotating it, the movements bec...

Mirroring right arm to the left on scapulothoracic model

Hello, As a brief context, I'm developing an upper body model to record four movements: arm flexion, abduction and rotation, and shoulder elevation. The arms' movements are fine, but the shoulder elevation reports incorrect orientation values for the coordinates. When elevating the shoulder, I expec...
