In this video, augustus is used to predict genes in example_nucleotide_sequence.fasta.
This results in a genome annotation file: augustus_example.gff.
The script getAnnoFasta.pl is used to extract the amino acid sequences in this genome annotation file to a new FASTA amino acid file: augustus_example.aa.
The mv command is used to change the extension of this file from “.aa” to “.faa”.
