Identification of ortholog is one of the important tasks to understand a novel genome. It helps to assign functional annotations,
from one organism to another organism. To identify the putative ortholog, Reciprocal Best BLAST hit (RBBH) method is known to
be an efficient approach. OrFin makes use of the same approach to identify pair of orthologous proteins for a given set of sequences
of two species. It is a user-friendly web tool which works with user defined parameters to search RBBHs. Results are produced in
both html and text format.
