Webb11 juli 2014 · Reciprocal Best Hits (RBH) are a common proxy for orthology in comparative genomics. Essentially, a RBH is found when the proteins encoded by two genes, each in a different genome, find each other as the best scoring match in the other genome. NCBI's BLAST is the software most usually used for the sequence comparisons necessary to … Webb1 feb. 2008 · Abstract.

For a full list of changes, see the [git commit log][log] and pick the appropriate rele WebbThe Reciprocal Best Hit (RBH) approach is commonly used in bioinformatics to show that two sequences evolved from a common ancestral gene. In other words, RBH tries to find orthologous protein sequences within and between species. These orthologous sequences can be further analysed to evaluate protein family evolution, infer phylogenetic trees ... Webb22 feb. 2012 · We have developed an iterative orthology prediction method, Ortho-Profile, that uses reciprocal best hits at the level of sequence profiles to infer orthology. It increases ortholog detection by 20% compared to sequence-to-sequence comparisons. self cursing
