File Information
Description

SimBiology project file and some associated MATLAB files that contain a generic and adaptable PBPK model. Human fasted, Human fed and Rat (new!) physiologies are included as variants.

Tested on R2012a and R2011b and should work with earlier releases as well. Does not contain tasks or the Renin-Angiotensin model as used in the June 2012 webinar. Please see http://www.mathworks.com/matlabcentral/fileexchange/37132-physiologically-based-pharmacokinetic-pbpk-model-for-simbiology for the project used in that webinar.

Oh! Sorry. There were answers already. It's working well now. Thank you.

When I run this model file, there were 14 errors. Belows are error messages.

"The name 'calculateParacellularAbsorption' in rule 'Paracellular Absorption' does not refer to any in-scope species, parameters, or compartments",
"The name 'calculateTissuePartition' in rule 'Adipose Tissue Partition Coefficient' does not refer to any in-scope species, parameters, or compartments."
and same message for bone, brain, gut, heart, liver, lung, muscle, pancreas, skin, thymus, spleen. What should I do?

Hi,
Duh ! As a long time user I should have figured that one out !!! Many thanks for reminding me !!

Hi Raj,
the first warning should not concern you, everything will work fine.
The error message is also slightly misleading. The download file contains two additional files (calculate...). These must be on the MATLAB path as they are called by SimBiology when you try to run the model. Either add the folder to the MATLAB path or navigate in the MATLAB Desktop to the folder. Does this solve your problems?

Hi
This is an excellent tool but doesn't work in my 2012a version. Upon opening the project file, Simbiology complains as follows:

"The SB project version being loaded is newer than the SB version being run. Some features of the project may not be supported in this version"

Also, the additional rules don't work ("does not refer to any in-scope species, parameters or compartment").

Any ideas?
