Hello Victoria, I believe that you could set the megahubs limit to a 1. add -SK:mmhr=1 (for 1 % megahub accepted) Which version are you using? I work with V 4.0. and I found that the megahub limit is set up to 90. I do not if this right. Maybe Bastien could have a suggestion. My case seems to be more dramatical!. I have more than 90 Thanks On Wed, Jun 25, 2014 at 11:36 AM, Offord, Victoria <vofford@xxxxxxxxx> wrote: > Hi, > > > > My MIRA run on a parasite transcriptome keeps ending with: > > > > You have 0.1052271917% of your reads as megahubs. > > You have set a maximum allowed ratio of: 0.0000000000 > > > > Ending the assembly because the maximum ratio has been reached/surpassed. > > Failure, wrapped MIRA process aborted. > > > > Does anyone have any advice on how I can avoid this?
