Newbie-list file (filename.fn.list)

Dear all,
I’m trying to analyse a set of sequences using MOTHUR and would like to use OTU analysing tools that are present in MOTHUR. The problem I’m coming up with is everything I want to do needs a list of my sequences first. How do I get this type of output that reads “filename.fn.list”?
Thank you so much

You might start with and see how far you get. You need to run cluster to assign sequences to OTUs (nb: fn is for furthest neighbor clustering and an is average neighbor and is preferred at this point).
