here is my code 
【qiime dada2 denoise-paired --i-demultiplexed-seqs ~/databac/res/raw.qza --p-trim-left-f 0 --p-trim-left-r 0 --p-trunc-len-f 220 --p-trunc-len-r 250 --o-table ~/databac/res/table.qza --o-representative-sequences ~/databac/res/seqs.qza --o-denoising-stats ~/databac/res/denoising-stats.qza --p-n-threads 0 】
