merging beta diversity

Can we merge beta diversity (e.g. Jaccard) from two different runs of two related datasets? instead of running everything from the beginning.

I can give a qiime-suggestion, but I can’t tell you if it’s statistically principled. So maybe it would be inappropriate or false to do—I don’t know enough to determine that—but you can do it.

Run, e.g., qiime diversity beta --help. You’ll see that all it needs as inputs are a feature table and your choice of metric (like Jaccard). So you can get what you want by finding the beta-diversity of a merged feature table, and you can get a merged feature table with qiime feature-table merge.

Hope this helped!
