Estimation from SFS; tpl error extinct deme

[大藤心旅]

Hello and thank you for any help!

I am trying to perform demographic inference from the SFS and am running into some issues with figuring out the tpl file. I attach a diagram of the models I am trying to define in the tpl and est files.

As you can see, it is a 3 group branching model. Running fsc27 with the attached tpl and est files, we get the following

> fsc27093 -t ${PREFIX}.tpl -e ${PREFIX}.est -P -c 1 -B 1 -0 -m -C 1 -n 100000  -L 50 -s 0 -M -E

 >Error: deme 807416884 going extinct while still having remaining lineages

I would love if someone could look over my tpl and est files and help me see what I am missing.

Thank you for your help!
