GenBank Feature Extractor accepts a GenBank file as input and reads the sequence feature information described in the feature table, according to the rules outlined in the GenBank release notes. The program extracts or highlights the relevant sequence segments and returns each sequence feature in FASTA format. GenBank Feature Extractor is particularly helpful when you wish to derive the sequence of a cDNA from a genomic sequence that contains many introns.
