Neighbor Joining Tree Missing

[Allison Stricker]

I have finished running my data and my neighbor joining tree shows nothing when I attempt to open it in the program.

I have 14 populations that I am looking at and 4 different assumed populations (K=3, K=4, K=5, and K=6). 

I was unable to see any of the neighbor joining trees on my initial parameter set as well.

Any help is greatly appreciated!
