Tax4Fun function annotation clustering heat map.According to the functional annotation and abundance information of the samples in the data, the top 25 functions in the list of abundance and the abundance information of each group of samples were selected to draw a heat map, and the clustering was conducted from the level of functional differences.Functional notes are on the right side of the heat map, and test groups are on the lower side of the heat map.In the heat map, the red color represents the higher relative abundance of functions, and the relative abundance increases with the deepening of the color.Blue represents the higher the relative abundance of the function, and with the deepening of the color, the relative abundance decreases
