Hi, I´m trying to build a heatmap from feature-table using taxonomy and metadata info. My issue is that I don´t know how to visualize only genera names in the heatmap (instead of all the taxonomic info. I´m using that script:
Hi @Manuss_Ponce,
Great question! Unfortunately, the answer is that there is no way to customize the names in QIIME 2 — easily.
You will need to export your taxonomy file, change the names to whatever you want, and re-import. Then collapse your feature table and build a heatmap using that taxonomy file.
Does that work for you? Sorry there’s not an easier way!
Hi Hupf!
What I did was to select the 50 features with higher median of relative frequencies (I don´t know if this approach is correct, I would accept some advise). I did it by hand in excel, exporting the feature table. Then, I built a metadata file with 2 colums: one with the OTU ids and another with the values TRUE or FALSE (the latter if each feature belongs to the top 50). Then I followed this:
I first built another heatmap using a table with the top 50 features in terms of total absolute abundance, but It doesn´t convince me, because of the associated bias. Maybe someone could provide another perspective, I,m quite neophyte in that field!!
