How to view unweighted unifrac distance matrix .qza file values

Hi all,

How can I see the values of an unweighted unifrac distance matrix? I have an unweighted_unifrac_distance_matrix.qza file, and I guess I need to convert it into a .qzv file but I don’t know how.

Hi @arturo,
Depending on what you are trying to do with that information there are several plugins that take distance matrices as input and provide a visualization.
For example check out the emepror plugin that produces PCoA-based plots. The longitudinal plugin can use these as well, see this tutorial for some examples. There are some visualizers and tests in the diversity plugins that take as input these distant matrices, for example the adonis and beta-group significance tests there etc.
Anyways, there are lots of different ways to use these and they depend on your question at hand, browsing through the tutorials can also give you a good idea when these are used.
Good luck!

Just want to add to @Mehrbod_Estaki’s excellent directions:

If you literally want to see the individual distances between samples, you will need to export your data using qiime tools export. This will give you a distance matrix, which is not too useful on its own usually — you probably want to use something like qiime diversity beta-group-significance to see the distribution of distances between samples in different metadata groups.

Thanks @Mehrbod_Estaki and @Nicholas_Bokulich,

yes @Nicholas_Bokulich I wanted to see exactly the individual distances. I have been able to do this with qiime tools export. Then I used the data to build a Heatmap with Plotly.
