Translate Genbank nucleotide files

The Genbank file format and Embl file format are widely used file formats for annotated nucleotide sequences (format specifications: http://www.ncbi.nlm.nih.gov/Sitemap/samplerecord.html and ftp://ftp.ncbi.nih.gov/genbank/gbrel.txt and http://www.ebi.ac.uk/embl/Documentation/User_manual/usrman.html). After loading a Genbank or Embl file, the nucleotide sequence is initially shown. Only after translation into amino acids, the amino acid sequence is shown. The translation is directed by a the CDS-sequence-features within the protein file. Example: 
   CDS     5. .799
   /gene="Psmb5"
   /product="proteasome subunit X"
If the Genbank file contains several genes the user can choose one of them.
