Re: Analyze MuscleAnalysis outputs different to plotter

Thank you! With "Solve for equilibrium for actuator states" selected I get outputs that vary in time from in the output Normalizedfiberlength.sto file. I note in the messages view there are some errors (see below), which I presume reduce the confidence I should have with the outputs produced. I'm un...

Re: Analyze MuscleAnalysis outputs different to plotter

Thank you for your reply. I have been plotting Normalized fiber length v IK results in the plotter - and this appears to show the outputs v time (the outputs from the IK e.g. pelvic tilt when plotted against time are exactly the same when plotted against IK results). I have been using the same IK re...

Analyze MuscleAnalysis outputs different to plotter

Hi, I am using the osim model gait2392_AlteredPelvisFrame3DoFkneeNoTorso.osim to process retrospective clinical gait data (Vicon PiG) from our gait lab. Following scaling, I have run the Inverse Kinematic tool using converted marker data from a trial as an input. The intention is to output key muscl...

Re: Adjust model markers - failing to place markers on model

Update - Seems to the the static.trc file that is the problem. I created it using MOtoNMS2.2, however comparing it to the files in the tutorial there were a couple of extra tabs. The scaling is now running the whole way through and adding the markers, now the tabs have been added in.

Adjust model markers - failing to place markers on model

Hi, I am struggling with the Scale Tool - specifically 'Adjust Model Markers' in OpenSim 4.3. I am using an adapted .osim model based on gait2392 and using marker data from a static standing trial, converted to .trc format (files attached -N.B. I have changed the static1.trc file extension to .txt t...

Re: Error during scaling. Step 3: placing marker on the model

Hi Giulia, I am also having this problem - did you ever resolve? I'm new to OpenSim but been through all guides, tutorials, and this forum, and can't seem to find the answer. I'm using a modified gait2392 model and a marker set from our clinical lab. Prior to the scaling tool getting stuck, all scal...
