Alpha Diversity Summary Statistics

Hi everyone,

I am calculaing some summary statistics using my .shared file which seemingly is straightforward, however when I run the following command:

summary.shared(shared=stability.trim.contigs.good.unique.good.filter.unique.precluster.pick.pick.an.unique_list.0.01.subsample.shared)

I get a table that lists each of my samples twice as shown below. Does anyone know the significance of this?

first is average, second is standard deviation

Thanks so much!! Is there a page you can direct me to that explains/describes the various parameters of the output?

There should be a column in there that says ave or sd - did you remove that? I’d encourage you to click on the links in the SOP to see what summary.single and the other commands are doing.
