Ｈello,
I want to distribution of species annotation information for gene sequences. At first, I use the blastn to do blast use NT database.
Then, I want to import the xml format data into the MEGA6, use the LCA algorithm．How do I set the LCA parameters? And export the informations about the classification information．
Like this:

  1. a fasta file:

gene1
…
gene2
…
gene3
…

  1. use the blastn get a xml documenｔ, -max_target_seqs 5
  2. import the xml document to the magn6, and use the LCA algorithm to get a ｂｅｓｔ one taxonomy information.
    How can I set the LCA parameters and export a document containing taxonomy information?
    Like this:

gene1 taxonomy
…
gene2 taxonomy
…
gene3 taxonomy
