I built a simple drug and dose model, I try to use GSA and mpgsa method, but when I finished setting up and pressed run, it says that "unable to plot gsa empty result"

Hi I am facing the following issue with model analyzer when trying to work with GSA program. I am unable to run this program and get the following errors SeverityMessage errorTest of generated MATLAB function failed. errorVerification of scenarios failed. Additionally, as I open matlab, the command window shows this message not sure if it is related to my problem, Caught "std::exception" Exception message is: An error occurred while initializing child process: While attempting to execute "C:\Program Files\MATLAB\R2022b\bin\win64\mwdocsearch.exe server -m C:\Program Files\MATLAB\R2022b -p 49970 -i 8980 -v C:\Users\WANG_G~1\AppData\Local\Temp\": CreateProcessW: Insufficient system resources exist to complete the requested service Could someone please let me know what these errors mean. Thank you

Hello, When using the sbiosobol function, what's the default distribution that is used to sample between the bounds? Is there a way to specify uniform distributions for some parameters and log-uniform for others? I know that this can be done by changing the structural model so that the log-uniform parameters are used e.g. as 10^k, but I am wondering if there's a way to do this without modifying the model? Thank you, Abed

Hello all, I've been using simbiology as part of an effort to run sensitivity analysis on a PDPK model as part of my masters. It's industry sponsored so the image below has the important information blurred but enough to give context. The black lines are simple mass kinetics, easily done in Simbiology. The green lines, howeever, are stimulations, i.e. there's no actual transfer of material, just its pressence causes an effect. I had thought these would be quite easily by creating a reaction from 'null -> x' and but I'm unsure on how to create that custom dependency, i.e. a null -> x where the equation is kyx*[y] -> x. It was easy to do on the GUI, however, the GUI dosn't quite have the freedom I need for sentitivity analysis. I was struggling to get a global sensitivity analysis going, basically. If anyone has any suggestions about either of these topics, that would be greatly appreciated. Many thanks, Dan
