Re: programming error

If you want to do frame based translation then there is an easier way of accomplishing this. The TranscriptionEngine allows you to translate in multiple frames and retrieve that information in a Map such as:

TranscriptionEngine te = TranscriptionEngine.getDefault();
Frame[] frames = Frame.getForwardFrames();
Map<Frame, Sequence<AminoAcidCompound>> results = te.multipleFrameTranslation(dna, frames);

Change the static call on Frame to Frame.getAllFrames() then you will do a full 6 frame translation.

Also I would avoid calling the getSequenceAsString() method until you need to output it to screen. The Sequence interface provides an adequate set of methods for testing length of a sequence. However if you want is the longest translation then I would replace that with (assuming the above code):

List<Sequence<AminoAcidCompound>> translations = new ArrayList<Sequence<AminoAcidCompound>>(results.getValues());
Collections.sort(translations, new Comparator<Sequence<AminoAcidCompound>>() {
  public int compare(Sequence<AminoAcidCompound> o1, Sequence<AminoAcidCompound> o2) {
    Integer o1Length = o1.getLength();
    Integer o2Length = o2.getLength();
    return o1Length.compareTo(o2Length);
  }
});
Sequence<AminoAcidCompound> longest = translations.get(translations.size()-1);

However I would like to see what errors you are pulling up from BioJava3 in case there is a scenario we are not currently taking into account
