Hello,
I am following the 16S Microbial Analysis with mothur (extended).
I sequenced the v3v4 region using 341F and 806R primers.
The fragment length is 470 bp.
I just wasn’t to make sure I am entering the right parameters during my analysis since the training was done on the v4 region.
First Screen.seqs: I am using 480 bp for fragment length
Second Screen.seqs: “start” : 6352 and “end”: 25433 according to the mean values in the log file of the previous step.
Pre.cluster: Should I be using diff 2 or 4? Since it is 1 in every 100 bases and I have a 470 bp fragment…
Thank you!
Stephanie
