Hi, Adam: First, thanks a lot for providing this code. (it is really great!) And I want to ask, each time when I start fitting, there exists warning infomation (about MultiNest): (start here)

Bagpipes: fitting object 17533

I know little about the MultiNest but I am sure that the MultiNest and pymultinest are installed properly on my machine. Could you please tell me whether the existence of warning information will influence my results? Anything from you will be appreciated! Thanks you again for making this code available!

Nothing to worry about. This is just the code telling you it's starting from scratch rather than carrying on a partially completed fit.

Thanks you!!!
