Just as a heads up the classifier in this post is a bit old and there are certainly newer versions of this calssifier trained with more recent version of scikit learn floating around the forum.
I didn’t actually set any range in my extraction, just left them at the defaults (which is min length 50). With curated databases I wasn’t too worried about the ranges during the extraction because, well, there shouldn’t be any junk in there anyways. If I was extracting reads from uncurated sources, like NCBI I would probably set ranges. By the way, you can check the parameter settings in the provenance tab of these too!
