It is required for the part that I need, so I'm wondering how to fix this. Then when I continue the next part, I get an error of "invalid keys as arguments" for setting tdata=[0,20] so I am unsure how to get this working. Any help would be great. Thank you.

I'm also curious if this is needed to run the remainder of the tutorial, which is the part I need; to iterate a bunch of phase plane solutions while varying a parameter. Would this error have any effect on that or would it be sufficient to continue and vary a parameter and I should still get the multiple phase plane solutions as required? Thanks!

Hello. I have a 2D system of ODEs and I am trying to plot the nullclines to then vary my model parameters and plot the effects based on the Zero-crossing events tutorial. Based on the current parameter set, I have three steady states (nullclines are verified using XPP but I digress). My goal is to plot multiple nullclines as a parameter (or parameters) vary to see what my model does. I have currently gotten through the portion where the nullclines are plotted but based on the settings, my figure...
