Storage Error Message when importing Visual3D Motion File

[Sara Elnahhas]

Hello!

I am new to OpenSim and I am currently helping with a project that requires getting our motion files from Visual3D to OpenSim.
I've made sure that the motion in Visual3D matches the requirements for OpenSim (in terms of orientation and scaling).
After exporting to an OpenSim motion file and trying to the load the motion onto a scaled OpenSim model, I keep getting the following error message:
Storage: ERROR - no more lines in storage file.
I played around with the range of frames exported from Visual3D (I went as low as only 10 frames in the middle of the motion) but I still keep getting this message and I am not sure where my issue is.

Thank you so much!

Best,
Sara Elnahhas

Hi Sara,

The likely issue is that the formatting of the header of the file is different from what OpenSim expects (extra spaces, trailing tabs, missing endheader token, etc. that confuse the parsing). This typically happens when you write/edit the files manually or in other tools (e.g. Excel, Matlab etc.). I suggest you compare the header of the file in question with the header from a file from the distribution that works. The documentation of the various formats is described here

Hope this helps,
