[Tutorial] Comparative Genomics of Vibrio cholerae
Welcome! This tutorial was prepared using a well-known pathogenic species, Vibrio cholerae, (the causal agent of cholera). It is a step-by-step example showing how to
Tetra-Nucleotide Analysis (TNA)
A tetra-nucleotide is a fragment of DNA sequence with 4 bases (e.g. AGTC or TTGG). Pride et al. (2003) showed that the frequency of tetra-nucleotides
Overall genome relatedness index (OGRI)
Overall genome relatedness index (OGRI) is a term first coined by Chun & Rainey (2014) and represents any measurements indicating how similar two genome sequences
OrthoANI genomic similarity
OrthoANI (Orthologous Average Nucleotide Identity) is a kind of similarity values between two genome sequences. It is an improved version of the original ANI (Average
