Problem in Cluster.split

I ran the cluster.split:
cluster.split(fasta=Kasht.trim.unique.good.filter.unique.precluster.pick.pick.fasta, count=Kasht.trim.unique.good.filter.unique.precluster.denovo.uchime.pick.pick.count_table,, splitmethod=classify, taxlevel=4, cutoff=0.15)
Then, I did not get the output file of merge file:
I got the separated file of .an.list file (including 212 files)
Do you know how I merge above list files following my group files to make share or I have to used merge command for all above files? Because I don’t know the separated list files from which groups? or How I make.shared with the separated list files?
thank you very much,

I suspect it crashed before it was done running. cluster.split will clean this up for you. Can you look back and see whether you got an error message?
