merging beta diversity

[khemlalnirmalkar]

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

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!
