Creates a summary report for sintax
predictions giving the frequencies of each named taxon at a given rank. For
example, at phylum rank, the report might show 25% Bacteroidetes, 18%
Input is an tabbed text output file from the
sintax command using the tabbedout option.
The rank option is required, it is a single letter specifying the rank, e.g.
p for phylum. See taxonomy annotations for
An OTU table can be specified using the
otutabin option. This will generate a report with frequencies for each
sample and over all samples combined. The table must be in
QIIME classic format. OTU identifiers in
the OTU table must exactly match the labels in the sintax output file.
If size annotations are found in the sequence
labels in the sintax output file, they are taken into account in calculating
The output from sintax_summary can be imported into a spreadsheet or
charting program for making figures.
