Re: [SOSlib-devel] Question regarding dimension of sensitivity matrix.

[Rainer M. <ra...@tb...>]

Hi Eryk,

sorry for still not having answered your previous emails.
Today was our last meeting for a while and I will have more time.

This one is answered fast.

because the model also has a compartment with size 1. Compartments in SBML 
are treated as constant parameters in odeModel.

Unfortunately we currently cannot do sens.analysis for selected parameters 
but for all parameters. Thus there is also a sensitivity for the 
compartment.
