argument of type 'NoneType' is not iterable

Dear Sir/Madam, Hope everything is going well with you. The following error occurred when I wanted to process data using OpenCap local deployment (Figure 1). Then I carefully checked the local code of this trial, only to find that the synchronized videos failed to download with the codes on the left...

Re: Kinematic data

Hi Antoine, Thanks for your reply. I've noticed that in the setup for inverse kinematics (IK), the weights assigned to various MarkerTasks vary from 5 to 30. Could you please explain the reasons for these differences? What factors should be considered when resetting the IK setup? Moreover, I can't f...

Kinematic data

Hi, Hope everything is going well with you. When I analyzed the hip joint angle during a crouch gait, I encountered a discrepancy of 40 degrees between two calculations. Using the locally deployed OpenCap with IKCoordinateTask, where there are no restrictions on the hip, knee, and ankle joints, but ...

Tests for the children with abnormal gait patterns

Hi, Hope everything is going well with you. In my research on children with cerebral palsy who suffer crouch gait or toe walking, I noticed that the values and weights in the IK Marker Task and IK Coordinate Task differ from those of the healthy group. Moreover, these values and weights significantl...

CoM Calculation for the children

Dear Sir/Madam I hope all is well with you. With your assistance, I have managed to understand how to find the location of the segmental CoM and segmental mass with the model in the OpenSim code. But I fail to find the principle about how to calculate the segmental CoM (for example, the CoM in the p...

Re: Calculation of CoM

Hi, Thank you for your response, and I hope all is well with you. With your assistance, I have managed to understand how to calculate the Center of Mass (CoM) in OpenCap, which involves segmental mass and the segmental CoM. I am researching children's gait and need to calculate their CoM. The ratios...

Calculation of CoM

Hi,

Hope everything is going well with you.

I want to calculate the center of mass (CoM) for children during gait but have been unable to find any relevant code. Could you please assist me with this?

Best regards,

Gait analysis in clinic

Hi, We will have gait analysis for the children with cerebral palsy with OpenCap, but we find that the children with crouch gait fail to have an ideal calibration perspective because they can't straighten their legs. Is standing with assistive devices, such as knee-ankle-foot orthosis, a good method...
