Just wanted to raise a separate issue on this in hope of having this function added.

Continuing the discussion from [Gneiss questions](https://forum.qiime2.org/t/gneiss-questions/1284/9):

> The downloaded pvalue coefficients aren’t FDR adjusted – but the visualized pvalues in the heatmap in Visualization Artifact does have FDR calculations. Right now, those pvalues will need to be corrected after download (we can raise an issue for this if we want to add FDR pvalues on download)

I'm working with a dataset that has a large number of balances to the point where the interactive heat-map plot of the regression\_summary.qzv appears all white at first glance. I have to zoom in quite a bit to see the individual colors of the heat-map and pan around quite a bit to find the potentially interesting balances. It also is very hard to read x-axis label when there are so many balances. Having the mentioned table above would help greatly in identifying interesting balances to explore downstream.

Thanks!

@Mehrbod_Estaki just added in a PR to download FDR corrected pvalues [here](https://github.com/biocore/gneiss/pull/257). So that should be ready by the next release.

It is also probably worthwhile to note that there should there be a way to take account of the hierarchy of the balances when performing the p-value correction. Not sure how to do it, and is probably an open question.
