Hi there, @XELong :)

If you want to be able to follow the tutorial with your data, including all the things that use the color column (which is most of the plots), then you'd need to have a column called "color" sample_info_tab, and it needs to hold names of colors based on the groups you care about. You can do this outside of R if it's easier, and then just read in the new sample_info.tsv that has the color column. If you look at the tutorial example data, you can see how that column is formatted, e.g., here is peaking at the file at the command-line:

So you'd want to add that column, with colors based on what makes sense for your data. For example, in the tutorial it's by what's the "char" column (water = blue; glassy = black; and so on). One place you can see a list of valid R colors and their names is at this page: https://r-graph-gallery.com/42-colors-names.html

If you don't have a "color" column that holds these color names for your data, then you will need to modify the code accordingly in many places. It's not as easy as me saying what to do where, unfortunately, it'd take running through all the exact code with the data files in order to make sure all different places are set accordingly. Sorry i don't have a version without colors

hope that helps
