regarding the barcodes

Ah OK. I was not sure if you had a new data set, or if this was the data set from your last thread:

My advice is the same. Use cutadapt, which will remove barcodes for you!

Given that you have forward reads, I would suggest
qiime cutadapt demux-single

Let me know if you have any questions!
