Normalise OpenSim data output to plot against experimental data in MATLAB
Hi, I am attempting to plot and normalise my data from OpenSim as a percentage of the gait cycle in order to compare against my experimental results (which are normalised) and verify the accuracy of my OpenSim analysis. I would like my OpenSim data to be normalised to the gait cycle so that there ar...

Re: Model Measurements
This is all relatively new to me and does not make much sense. If you place markers on the model and compute the distances between the pairs of markers using the x,y,z coordinates (are these in metres?), you do not get a uniformly distributed scaling factor. Instead there is a large disparity betwee...

Model Measurements
I am attempting to calculate the scale factor for my OpenSim comparison. I have the experimental data (e) and measurements but cannot seem to find any measurements for the model(m) to be able to compute the scale factors for each body part via the prescribed formula s = e/m. I am using the gait2354 ...

Model Measurements
Hello, I am attempting to compute the scale factors for my model but am unable to locate the length of body parts used in the model gait2354 (or any model for that matter). I thought the scale factor is computed using s = e/m and I have the e values but not the m values. Please help me locate the re...

Re: Change parameters such as Height, Age and Weight
I too am very confused about how to calculate the scaling factor. If it is just an "overall scale factor s can then be used to scale any segments, and along any combination of the X, Y, and Z axe" how does the values for each body segment change? Where do you even find the model (say gait2354) dista...
