Value Error: matting.cpp: 1728

[natashaserrao]

Hi Bo,

I am so sorry for all of my questions and that I am struggling with the trivial stuff- I am having a really hard time trying to create my simulation!

My code was working fine till I assigned ages to the individuals using a specified error, after which I kept getting the following message, "ValueError: mating.cpp: 1728 An exact (all negative) weight system is used, but does not fill offspring subpopulation."

Thoughts?

Thank you, Natasha

The error message says

1. You have weight -1 for clone mating, which copies all individuals to the offspring generation.
2. The second mating scheme should have weight 0, and generate the rest of the offspring. If you get an error, it probably means the parental virtual subpopulation is empty.

The best way to debug this is to print the size of all (virtual) subpopulations before mating (using a preMating operator, or in a demo function).

Thanks Bo!

I have resolved that issue, and get a new error, TypeError: in method 'new_HomoMating', argument 3 of type 'simuPOP::uintListFunc const &'.

I am trying to use the ExpansionEvent model and am running into problems. I can do this successfully without age structuring, but as soon as I add in the age structuring, it gives me that error.

I would love any insight on how to debug this error!

Thank you for your sustained help, Natasha

Please read the manual more carefully. ExpansionEvent by itself is a event and should be used inside a EventBasedModel.
