Why does Simbiology say my data doesn't contain a numeric value?

5 views (last 30 days)
I'm trying to run a data fit with experimental data. Every time I run data fit, Simbiology gives me the error: Dataset must contain at least one numeric variable. The dataset looks fine and has many numeric values. What could be going on?

You can attach files to posts here. Do you see the symbol for this?

Hi,
I have exactly the same problem. I tried to make a very simple model to solve this error but I didn't manage to do so yet.
I added the sbproj file and the mat file of the simple model in attachment. I try to estimate the parameter param1 on Dataset1. The first column is time, the 2nd column is the drug concentration in compartment1. You can find all of this in the 'Fit data'-task.
I'm also very new to SimBiology and I also use the SimBiology desktop (so not the command line).
Thank you very much.

Thanks for the quick replies! The data set is a 231x2 vector of class double from my matlab worksopace. One column is time and the other column is concentration. I don't think it is the cell array issue.
I am using SimBiology desktop, not using the command line. I'm using Matlab2014a. I have 2 reactions with five variables and five parameters (kinetic rate constants). I have data for the concentration of the product that is made in time. I'm asking Simbiology to fit the 5 rates (for which I have a good guess) and it runs the fit for a while and then at the end it says the dataset must contain a numeric variable and then that the model is overparameterized. Maybe it is something about the dataset, but I'm not sure what to try, I'm new to Simbiology but a Matlab veteran of sorts. :-D
Thanks for the help
How do I share the data and .sbproj here?
