Hi I have D-loop CO1 sequences gained from automated sequencer. I export abi fails to fasta format and then import in MEGA to align and analyze. However, after alignment, sequences are includes stop codons. what can I do to correct my data? I tried to shift frame but there are lots of gaps within the sequences after alignment. I am fully confused. can anyone suggest what can I do or indicate proper literature? I could not find solutions in various introductory books in phylogenetics and bioinformatics
If you really had stop codons you would need to think about whether you'd amplified the gene your were aiming for. Since the d-loop isn't protein-coding you can't have stop (or any other) codons.
"abi fails"? Do you mean "abi files"? Sounds like the simplest solution would be to remove stop codons from the sequences before alignment.
