## Description

This is a graph of the amount of pile-up alignments we are getting when monDom4 is aligned to Hg18 on just chr22. The graph height at any particular location is a count of the number of different monDom4 alignments overlapping at that chr22 position in Hg18. There are three hot spots on Hg18 chr22 with thousands of hits from monDom4. Namely:

- chr22: 15000000 - 16000000 - 25,912 monDom4 aligned pieces
- chr22: 19000000 - 20000000 - 10,524 monDom4 aligned pieces
- chr22: 22000000 - 23000000 - 14,133 monDom4 aligned pieces

It hasn't been measured, but I would expect similar patterns on other Hg18 chromosomes since our alignment counts on Hg18 are immense. This is just a sample from chr22 since it is small and easy to measure.
