An ngrams object is a DataFrame that contains count data of synteny patterns collected from a group of similar loci or genomes. It is produced by running anvi-analyze-synteny when given a genomes-storage-db and an annotation source.

An ngram is a group of neighboring genes that include precisely n genes, inspired by the term ngram in linguistics and natural language processing. This object was inspired by kmer count tables but is inherently different because it is counting adjacent genes and not nucleotides.
