KmerFreqCalc workflow and the data description. (A) The overview of the KmerFreqCalc workflow: (1) calculating the k-mer frequencies of each samples, (2) computing the distance between paired samples. (B) Two published metagenomic datasets including samples from wild giant pandas. The figure about partition of three stages and four food categories during 1 year in Qinling Mountains was adapted from “Seasonal variation in nutrient utilization shapes gut microbiome structure and function in wild giant pandas” (Wu et al., 2017) with permission. Above the time line is the four food categories. Below the time line is the three stages, in which the leaf, shoot, and transition stages are shown in green, orange, and gray, respectively.
