Problem Using of OpenSim tools( scaling TRC XML)

Please I am currently working on a project involving the use of a wrist model and very new to OpenSim

I am trying to use the scale tool, inverse kinematics and inverse dynamics

it is requested in the scale tool setting to add makers and marker data which would require an XML and TRC file

My question is on the directory folder for the wrist model these files are not given unlike Gait2392_simbkdy where the files are already given in the folder

Am I meant to create the XML and TRC to get my analysis

Also I have already tried to install resources using the scripting shell but it does not seem to work

You must add the virtual markers of the model according to the market placement during motion capture:

You can also find a lot of information in the user guide:

Thanks for the reply
I am just using only a motion file as the input without the use of any maker file

What tools can I use without adding a marker file

Can I be able to use these tools inverse kinematics, inverse dynamics and static optimisation

My generalised forces for my IDresults when I ran the analysis for inverse dynamics was 0
can this be because of no added external forces and do I have to create an sto file to get a result other than 0

Also when I run my analysis on static optimisation it takes a by long time to excecute and has been on zero since the start of the analysis
Is this common during the procedure
