status = CallForwardTool(modelDirectory, ...
modelFile, resultsDirectory, initialStatesFile). I get the following error on running it. Could you please suggest any help!

Hi Jan,

The likely culprit is using full/absolute pathname in the xml file where a relative path name is expected. Usually you don'tneed to specify full path if all the files are in the same folder as the setup file.

Hope this helps,

Dear Ayman,
Thanks for the quick reply, I tried using the filenames instead of the absolute path but I still get the error as below.
Thanks again!

The error message indicates that you are attempting to open a file called "UserFunctionsarm26.osim". The line armModel = Model([modelDirectory, modelFile]); concatenates the strings you provide as the modelDirectory and modelFile arguments, so assuming you have a directory named "UserFunctions" under the directory from which you're calling this function, you probably just need to add a "/" at the end of the first argument:

status = CallForwardTool('UserFunctions/', 'arm26.osim', etc.

Dear Tom,
I used the absolute path path the 1,3 input argument and followed your advice, its working now! Thanks for the help!

Best,
