Given a gene or a list of genes from a query organism, and a reference taxon, this programs returns the orthologs of the query gene(s) in all the organisms belonging to the reference taxon.
Query genes can be directly entered on the query input or in an input file.
The first word of each row of input file is considered as a query. Any additional information on the same row is ignored.
A tab-separated file with two (or more) columns. Each row of the output file describes one similarity between a query gene and another gene (ortholog or paralog, depending on the parameters).
The program returns at least these three first columns :
Additional columns can be specified :
Actually, this program allows to retrieve orthologs, but also paralogs.
The detection of pairwise similarities is based on a bidirectional BLAST of each genome against each other. During the detection phase, multiple hits for a single gene are allowed, and the user can decide to filter them out or not.
