16s microbiota data analysis based on XMAS package
Chapter 1 Prerequisites
Here, we give users one example to practice the 16s microbiota data analysis workflow by XMAS 2.0. By the way, we also recommend users handling your own microbiota data in a reasonable manner when you utilize this package or workflow. Pay attention to whether your data fit the methods this package provided.
1.1 Preparing for the tutorial
This tutorial requires that the users should have basic knowledge on R language and statistics. If you are new to microbial research, we recommend the Statistical Analysis of Microbiome Data with R (Xia et al. 2018) as guide book.
We suggest users using local laptop because our own server have not deployed XMAS 2.0 package yet. In addition, installing the following software before using XMAS 2.0.
