Thank you both with your help with this!
I'm using the exact same pipeline on this windows based virtual machine that I used with my personal Mac. Everything worked fine on my Mac. Could this be an issue with the virtual machine set up? I also ask since I have tried various number of vertices (as well as with FieldTrip), but am still running into the same error. For the time being, I will go through all the number of vertex options more thoroughly.
Thank you,
Paul
