Transposable Element Mapping – Crassostrea virginica NCBI Genome Assembly using RepeatMasker 4.07

Genome used: NCBI GCA_002022765.4_C_virginica-3.0

I ran RepeatMasker (v4.07) with RepBase-20170127 and RMBlast 2.6.0 with species set to Crassotrea virginica.

All commands were documented in a Jupyter Notebook (GitHub):
