This tab presents our earlier work for KMAP Ocean Gene Catalogue;  KEGG Modules Completeness numbers for two KEGG sulfate reduction modules are summarised for Ocean Gene Catalogue samples in the query results. We later implemented a generic method with EBI MGnify Team's KEGG Modules Completion project; available with the View option next to the Download option.  One particular feature of this tab; the completion calculations are restricted to the clusters selected by the running queries, as a result when a query is restrictive the samples processed and their completions could be few or none. Since our initial work, KEGG pathway definitions of these two modules were updated, we haven't updated our pathway models yet. We include this tab to have some history of our work.
