mNGS of cerebrospinal fluid: adult male
Each non-host sequence was aligned with the DNA sequences in the database using the principle of optimal similarity, and species information features from the database DNA sequences were utilized to summarize and merge the number of non-host sequences matched to different species. The pathogenic microbial reference genomes used for classification were downloaded from the National Center for Biotechnology Information (NCBI) (ftp://ftp.ncbi.nlm.nih.gov/genomes/) and other public databases.
