I tried using qiime feature-table filter-features to filter OTUs with minimum 1, 10, and 100 frequency. using below command
qiime feature-table filter-features
Everytime I get a filtered table of 17kb size while the input table size is 189kb.
When I put this output filtered table table100.qza in the
qiime feature-table heatmap
then i get this error
"Plugin error from feature-table: ‘Cannot visualize an empty table.’
If I put output table100.qza in qiime feature-table summarize
it gives me this error
Plugin error from feature-table: ids_to_keep must contain at least one ID.
Sounds like you filtered all features out of your table. You should check out your feature table with qiime feature-table summarize to see how many reads you have per feature and what you can afford to filter out.
