error message - Unrecognized function or variable ‘rec’.

On running a NAC (non-compartmental analysis) with Simbiology, below message was seen. What does it meam? Everything looked good.

"Unrecognized function or variable 'rec'."

[Arthur Goldsipe]

I see this variable mentioned in SimBiology's NCA code. But it's hard to tell what could be causing this specific error without more details. Can you share your version of MATLAB (for example, the output from running "ver")? And also can you share your SimBiology code or project that will reproduce this issue?

MATLAB Version 9.14 (R2023a)

SimBiology Version 6.4.1 (R2023a)

Attached is the project file with the error. It was tried using SB Model Analysier.

Answer 1

[Arthur Goldsipe]

Your NCA program is erroring because of problems with the first row in your data. If you change that first ID from 0 to 1, and that first Time from NaN to 0, then you can run the program without error. But please double-check that those are the values you intend.

As a side note, I would have expected you to receive a more informative error message for this mistake. I'll see if we can work on that.

Thanks Arthur!

You try to use the variable rec in your code, or try to call a function called rec. But that function or variable does not exist. Why do you think it should?

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
