Hi @matteofrigo @rutgerfick As mentioned before we are cascading a full ICVF map into a multi-tissue MCMDI 3 compartment model. We are inputting the tissue responses which are in the...

Hi @rutgerfick, Last we spoke we had discussed splitting up shells for calculations of various compartments. We have a dataset with _b=0,500,1000,2000_ and we were going to try and use...
