Weblogos of Metaviridae, Pseudoviridae and Retroviridae LTRs. (A) Weblogo for a Viterbi alignment of the Zam training set. Major insertions are indicated as red triangles with the number of inserts below them. The heights of the letters are a measure of how well conserved the residues are. Two bits correspond to 100% conservation. (B) Weblogo for a Viterbi alignment of the Mag A training set. (C)Weblogo for a Viterbi alignment of the Sushi training set. (D) Weblogo for a Viterbi alignment of the Retrofit training set. (E) Weblogo for a Viterbi alignment of the Sire training set. (F)Weblogo for a Viterbi alignment of the training set of class III retroviruses.
