[Biojava-dev] biojava3 sequence tools

[Andreas Prlic]

thanks for the replies. I was trying to see how to improve a web-form
into which the user can paste in any type of sequence and the server
selects the correct version of blast to run...  I will probably use a
check how many % of the sequence are looking like they are
nucleotides. Unlikely to find a longer protein sequence that just
consist of ATCGs ...

Every auto detector I've known gets it wrong since they all apply arbitrary thresholds to decide the switch.
