hi!
Are duplicate sequences removed for qiime feature-table merge and qiime feature-table merge-seqs? If the sequence is removed, does the frequencies merge and only one unique sequence remains?
thankyou.
Hi @kimshinseung,
Yes, the frequencies are merged by the ‘feature-table merge’ command, as described in:
https://docs.qiime2.org/2020.11/plugins/available/feature-table/merge/
But you have to set:
–p-overlap-method sum
Cheers
PS I edited the title of your question and delete dada2 which could be misleading
