mafft : progressive method #8

Closed mitchellcheung8 closed 5 years ago

mitchellcheung8 commented 5 years ago

I was running a targeted ngs experiment using the IMSindel tool. I got an error that indicates that mafft should be run in progressive mode (see error below). I am not familiar with Ruby, how do you add the "--retree 1" argument to the Ruby script that calls the mafft program. Thanks.

Thanks for report. Would you edit line 153-160 in consensus.rb as shown below.

      res, err, status = Open3.capture3(env,
                                        @mafft,
                                        '--nuc',

Thank you so much for showing me how to modify the parameters.

Best, Mitchell
