I am working on generating a heatmap using Qiime 2 in Virtualbox. I would like to show only data at the genus level for 6 samples. Firstly, I used qiime taxa filter-table to retain only features that were at annotated to the genus level. Then, I used ** qiime taxa collapse** to collapse features by their taxonomy at the genus level. Finally, I used ** qiime feature-table heatmap** to generate the heatmap. However, the x-axis still showing other taxa that only can annotate at order or family level. Also, in my output .qzv file, the taxa name is k_bacteria: p bacteroidetes:c sphingobacteria,o_ sphingobacteriales:f_ chitinophagaceae:g_arachidicoccus__, for example. I would like to show up the only genus name (e.g. arachidicoccus). I was wondering if qiime2 have any plugin that has this function. Below is the code I used to generate the heatmap.

This is the picture of the heatmap.
Thank you so much for spending your time reading my post.
