Trouble shoting of cluster

Dear Dr. Pschloss,

I tried
mothur > screen.seqs(fasta=./align/454.trim.cut.unique.align,name=./unique/454.trim.cut.names,group=./trim/454.groups,minlength=200,maxambig=0,maxhomop=8,processors=10, outputdir=./screen/, start=10352)

and

mothur > summary.seqs(fasta=./filter/454.trim.cut.unique.good.filter.fasta, name=./screen/454.trim.cut.good.names, processors=10)

and got this result

please help me

What is the output of summary.seqs on the output of screen.seqs? what you sent was the output from after running filter.seqs.
