[maker-devel] Curious pattern in AED distributions

[Lior Glick]

Hi MAKER users,
Lately I've been performing annotations for multiple genomes from the same
species.
When plotting the histogram of AED scores over all genes, I repeatedly see
a very specific pattern, that looks something like this:

This pattern is a bit surprising to me, in two aspects:
1) Why is there a surge towards 0.5?
2) Why is there a sudden drop right after that surge?

Has anyone else seen this, or is this a specific outcome of my
data/configuration?
Any ideas of what may cause such a distribution?

While this is not necessarily an indication of a problem or bug, it does
seem a bit odd, and  might imply some bias or artifact.
Would appreciate your comments.
Thank you!
