obtaining imuplacer outputs via matlab API

[Erik Wilmes]

Hi All,

I would like to know if it is possible to obtain the outputs of the IMUplacer (e.g. heading correction) in matlab. I am using OpenSim 4.3 via the matlab API on a mac. When a colleague runs the exact same matlab scripts to run the IMUplacer the outputs are printed to the matlab command window. However, they are not when I try it on my mac. The IMUplacer does work since I am able to use the calibrated model generated via the IMUplacer tool in the opensim GUI.

Thanks!

Kind regards,
Erik

Hello,

You can use the logging functionality introduced in version 4.2 and described below to customize/direct messages on all platforms:

Hope this helps,

Hi Ayman,

Thanks for the quick reply. Unfortunately this did not work. I got the following error when running the following code:

clear all; close all; clc;
import org.opensim.modeling.*

Logger.setLevel("Info");

Error:
No method 'org.opensim.modeling.Logger.setLevel' with matching signature found.

Error in calibrateOpenSimModelIMUs (line 22)
Logger.setLevel("Info");

Kind regards,
Erik

Please see the API documentation for the "Logger" class here: https://simtk.org/api_docs/opensim/api_ ... ogger.html. The argument to the setLevel() method is of type "Level" which is an enum (not a string). It looks like Level::Info is mapped to 2 (see the "enum Level" entry under "Public Types"), so the Matlab equivalent should be Logger.setLevel(2).

Thanks Tom,

I'd also add that there's a setLevelString method that takes a "String" input directly.

Best regards,
