Hi, I am assembling a microorgaism genome with over 200X Hifi reads, but canu told be that only 200X was selected for assembling, do you have any ideas on which part of it was selected?

Canu says this:

For genome size of 28000000 bases,
retain 5600000000 bases (200.00X coverage).

Found 1106878 reads with 20999061795 bases (749.97X coverage).
Dropped 811663 reads with 15399054876 bases (549.97X coverage).
Retained 295215 reads with 5600006919 bases (200.00X coverage).
