I have been using AnyBody to investigate the effects of total hip
replacement on the femur. However I now want to be able to move the
the position of the hip joint but use muscles calibrated as if the leg
had not been moved. I know that the calibration sequence must be run
before the inverse dynamic sequence to allow the programme to write out
the muscle tendon lengths and other parameters. But I want to then
change the geometry and re-run the model with the old calibration
results. Is there any way to store what the calibration sequence
creates and then use it in a subsequent model? I’ve looked at what I
think the calibration is creating but it seems that they are parameters
that cannot be accessed in the muscle models when orignially creating
them. Any thoughts or suggestions would be gratefully received.
Unfortunately the best solution is a lengthy one. Create a Outputfile and
write the tendon length data for all muscles after doing the calibration.
Then go the new, modified model and change the tendon length for the
muscles. When you automate the read in procedure it should be quite easy to
work with.

Thank you for your reply, its great to know that what I want to do is
possible! Unfortunately, I’m not quite sure how to implement your
suggestion. I can write an output file that contains the tendon
length (Lt), which changes at every time step, but I don’t know how
to make the modified model use it. The Lt is a denied access member
of the AnyViaPointMuscle type. Is there any way around this or have
I just got confused as to what I should be doing?
Thanks again for your help,
Catherine

The way will be to create the Outputfile in the Calibrationstudy. Next you
have to create a new MusclePar File, where all the muscle models are listed.
I would read in the Outputfile there and take the Lt0 values one by one with
indices referring to the entries. So each Muscle’s lt0 has a reference to
the according value in the created outputfile. This means that you don’t
need to run the calibration for the second model, as you have already the
optimised tendon length included.

length (Lt), which changes at every time step, but I don’t know how
to make the modified model use it. The Lt is a denied access member
of the AnyViaPointMuscle type. Is there any way around this or have

Thank you for your help. I have done what you suggested and it all
seems to be working!
