Hello everyone,

I am trying to compare two evolutive scenarios for two populations of fish in DIYABC (1 mtDNA locus)

Scenario 1:

P1 P2

0 sample 1

0 sample 2

t2 merge 1 2

Scenario 2:

P1 P2 GHO

0 sample 1

0 sample 2

t1 split 1 3 2 rm

t2 merge 3 2

(I have attached a file with the drawings)

after building the reference table, when I try to run the "estimate parameters" for scenario 2, using the admixture rate "rm" as a parameter (with a uniform prior between 0.001 - 0.999), I get this error message:

"Something happened during the analysis parameters : Program of thread 'parameters' exited (with return code -1073741819) unsuccessfully."

- When I set the admixture rate to any fixed value (0.5, for example) the analysis run without any problem.

- The other five analyses options (pre-evaluate scenarios/ compute posterior prob of scenarios / confidence in scenario choice/ compute bias and precision / model checking) run normally in any configuration

Does anyone have any idea about what is happening?

Thanks
