I would like to filter out asv’s below a certain length, because they seem to be sequencing artifacts. I am trying to use the very elegant solution posted here by @thermokarst
Filtering out ASVs from DADA2 based on length
However, nothing seems to be happening at the terminal window when I run this. The command I used was:
qiime feature-table filter-seqs \ --i-data rep-seqs.qza \ --m-metadata-file rep-seqs.qza \ --p-where 'length(sequence) > 350’ \ --o-filtered-data 350-seqs.qza
Am I using this correctly?
