Hello Rijal,

Take a look at [this thread](https://forum.qiime2.org/t/heatmap-qiime-feature-table-heatmap/2182) and the plugin [feature-table heatmap](https://docs.qiime2.org/2022.2/plugins/available/feature-table/heatmap/) for building a heatmap, and some of the functions that are helpful along the way.

For your first question, check out [qiime feature-table core-features](https://docs.qiime2.org/2022.2/plugins/available/feature-table/core-features/), which lets you identity the core bacteria with high prevalence across your samples _without_ a heatmap.

Of course, let us know if you have any questions!
