This analysis step will not alter the input file but count the number of reads assigned to each taxon ID. The results are stored to a temporary statistics file as comma-separated values (CSV) with taxon IDs in column taxon_id and the read counts in column read_count.
Up to 1000 of these steps can be included in a workflow to compare read counts between arbitrary filtering steps. The temporary files as well as the corresponding read count columns will be enumerated from 000 to 999 and compiled into one large spreadsheet during post-processing.
