I ran Quast to compare all of our current Olympia oyster genome assemblies.

See Jupyter Notebook in Results section for Quast execution.

Very enlightening!

BEST OF:

Largest Contig: redundans_sjw_02 (322,397bp) Total Length: soap_bgi_01 & pbjelly_sjw_01 (697,528,655bp) Total Length (>=50,000bp): redundans_sjw_03 (17,006,058bp) N50: redundans_sjw_03 (17,679bp)

Interesting tidbit: The pbjelly_sjw_01 assembly is EXACTLY the same as the soap_bgi_01. Looking at the output messages from that PB Jelly assembly, one can see why. The messages indicate that no gaps were filled on the BGI scaffold reference! That means the PB Jelly output is just the BGI scaffold reference assembly!
