Combining multiple OTU tables

My OTU and taxonomy results are in two separate tables (different samples in each). How can I combine these into one table in order to proceed with the workflow? Is this sound?

Thanks!

Since there is no context provided here, I can only give some general comments:

  • if all samples are from a single study, and the two tables are processed using the same workflow and same parameters, and features are ASV (i.e. DADA2 workflow), it is combinable. Make sure to combine based on the exact ASV sequences.
  • OTUs are generated based on clustering, and are usually data & algorithm specific. OTUs are in general not combinable or comparable across different data or workflows
