What is the difference between these two?

Why can't I find max_contraction_velocity in Thelen2003Muscle_Deprecated.

Thanks
John

Hi John,

Deprecated types are those we don't support anymore either because they are redundant or their implementation was incorrect. The Thelen2003muscle_Deprecated inherited the properties from activation_fibre_length_deprecated, which doesn't include max_contraction_velocity. The current Thelen2003muscle inherits from an updated version of activation_fibre_length, which does include max_contraction_velocity.

In this case, you would have to update to the current muscle model to access this property.

Hope that helps?

Thanks James.
I understand from your post that Thelen2003Muscle is more recent than the Deprecated version.
Someone advised me to use the deprecated version for a project (a project based on Sam Hamner's models), and now I am wondering why.
In what case might you want to use an old version of the muscle?
Thanks
John

Hi John,

The only case in which you would use the old versions is if you wanted to replicate previous results.
