Thank you for the help, although I'm still having some problems, I
think I might have narrowed down the causes.

I'm fairly certain that the "Array dimensions must be greater than 0"
error message is talking about the dims, which begins with a -1. I
have found out that this is because there is not pointer to the ROI I
have opened. I'm hoping that someone can give me guidance as to how I
can ensure that this pointer is created.

Jeff's suggestion that I didn't set class_ptr to anything makes sense
to me, but I can't find where to set it, any help would be greatly
appreciated.

Thanks,
Lauren
