Hierarchical clustering: comparing faeces to rumen samples. Hierarchical clustering of rumen and faecal samples from the same animals. Reads were aligned to a) DPI_rumen database, b) JGI_rumen database, c) Human Stool database. The distance matrix method used was Canberra. Bootstrap (bp) and approximately unbias (au) values were generated using Pvclust  with 1000 iterations.
