Hi Kristy, The easiest way to see if the muscle path changes are either a visualizer error or path error would be to plot the fiber length and moment arm curves for LAT1. This can be done with the plot tool, and I usually do a set of plots in the default posture and a set of plots with my posture se...

Hey Rob, All around good news that its just a saving issue (awesome that the core MTP processing can handle the difference in passive data formats). In the meantime I do have one questions about getting the rest of my MTP results to save since if appears saving the passive moments is the first step ...

Ahhh, I was curious how/why you all were able to get perfect single joint movements. So we are having to collect the passive movement data using motion capture (and subsequently OpenSim Inverse Kinematics) to get our joint angles. For cameras to successfully pick up markers the arm is held straight ...

We seem to have run into an issue tied to saving the results of the Length Initialization step when running it with the Muscle-Tendon Personalization pipeline. It looks like it is tied to how the data is Passive Moment Data is getting reshaped for the eventual sto file. I'm guessing it is tied to ei...

Posting an error associated with muscle naming conventions due to MatLab variable name rules. This error occurs during MTP when the optimized parameters are being saved. From my limited understanding of MatLab it appears that the names of a field within a structure are not allowed to start with a nu...

Hey Spencer, This was a huge help. Changing the '_force' roots to '_moment' worked for running MTP with and without Length Initialization. The wrist_hand_r1 coordinates was an error with our preprocessing code and how it was parsing and reconstructing names, so the file existed but with the wrong na...

Hi Spencer, A parsing error would make sense (I ran into a few when first trying to let the pipeline auto determine trial prefixes). I've attached zip files that have the workspaces associated with each function that go with the error messages that I get when placing a breakpoint at the failing line...

We are currently looking to run muscle-tendon length initialization and personalization on some muscles that cross 10 joints within the wrist, thumb, and index finger of the Mobl-Arms models. To get the pipeline running we are using three passive movement tasks and two active hand tasks (one trial e...
