```
# To calculate ancestry stuff:
admixture Finches_noSca.bed 4 # -j8 this last flag is to increase the number of cores!
Summary:
Converged in 40 iterations (1258.95 sec)
Loglikelihood: -39945324.128610
Fst divergences between estimated populations:
Pop0 Pop1 Pop2
Pop0
Pop1 0.016
Pop2 0.043 0.041
Pop3 0.014 0.017 0.041
Writing output files.
# Will output this:
Finches_noSca.4.Q Finches_noSca.4.P
```

Does it have something to do with this:

Point estimation will terminate when objective function delta < 0.0001
Estimation of standard errors disabled; will compute point estimates only.

The `3 secant conditions`
