AnnotationBustR Tutorial

This is a tutorial for using the R package AnnotationBustR. AnnotationBustR reads in sequences from GenBank and allows you to quickly extract specific parts and write them to FASTA files given a set of search terms. This is useful as it allows users to quickly extract parts of concatenated or genomic sequences based on GenBank features and write them to FASTA files, even when feature annotations for homologous loci may vary (i.e. gene synonyms like COI, COX1, COXI all being used for cytochrome oxidase subunit 1).
