I have an environmental seawater sample with 18s genomic data. I want to filter out all sequences that are not of a specific taxa, and I have done so in the feature table using the below script.
qiime taxa filter-table
Now that I have a feature table with only these sequences, I want to trim the rep-seqs file accordingly, so that when I use iTOL to visualize a phylogenetic tree I can see only the taxa of interest. However, I cannot seem to figure out how to trim the actual sequences so that all non-cryptophyceae are excluded. Any help would be appreciated, thanks!
