When I plot the joint moments of certain muscles over the joint angle I get results that seem OK. If I try to get the same results with the analyze tool with a predefined motion of the desired joint, my results seem quite strange.

Ayman wrote in https://simtk.org/forum/message.php?msg_id=4074 that one should define a states file with muscle.activation set to 1.0 for the desired muscles.

As I see some examples of states files in the tutorial, how can I actually add this file to the analzye-setup?
Is it OK to add additional columns in my 'motion describing.mot' that define the muscle states (e.g 1.0) of the desired muscles during the full motion?

Or in other words: How does an Analyze-tool setup look like if it generates the same results as the plot tool, when I want to calculate joint moments?

thx

Reinhard,

When you run the tools (AnalyzeTool in this case) you have the option to specify coordinates or states (xml tag=states_file).

You should be ok adding the columns in Excel just make sure it doesn't mess up the formatting and add extraneous tabs (particularly in the header).

Hope this helps,

Thx Ayman!

Was a little bit tricky to manually generate a working states file, but finally i got what i want
